What the test measures

Seeing Structure in Expressions skills

  1. A-SSE.A.1 Interpret expressions that represent a quantity in terms of its context

  2. A-SSE.A.2 Use the structure of an expression to identify ways to rewrite it

  3. A-SSE.B.3 Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression

  4. A-SSE.B.3a Factor a quadratic expression to reveal the zeros of the function it defines

  5. A-SSE.B.3b Complete the square in a quadratic expression to reveal the maximum or minimum value of the function it defines

  6. A-SSE.B.4 Derive the formula for the sum of a finite geometric series

Standards basis

New Jersey Student Learning Standards for Mathematics (NJSLS-M), aligned to Common Core State Standards for Mathematics (CCSS-M) — New Jersey

How the NJSLA reports it

NJSLA math is built on the New Jersey Student Learning Standards for Mathematics, which closely follow the Common Core domain structure and progressions. The assessment is organized by grade-level and end-of-course reporting aligned to those standards rather than by a separate proprietary framework.

Blueprint & weighting

NJDOE publishes statewide assessment administration information and grade/course coverage, but no official public math-domain weighting blueprint was located in the retrieved primary materials.

Which is a factored form of x2−8x+15x^2 - 8x + 15?

Find two numbers with product 1515 and sum −8-8: −3-3 and −5-5. So x2−8x+15=(x−3)(x−5)x^2 - 8x + 15 = (x-3)(x-5).

Use completing the square to rewrite the equation in vertex form.

y=−x2+6x−5y = -x^{2} + 6x - 5

Select the vertex form of the equation.

Factor out −1-1 from the xx terms, then complete the square: y=−(x2−6x+9−9)−5=−((x−3)2−9)−5=−(x−3)2+4.y = -(x^{2} - 6x + 9 - 9) - 5 = -((x - 3)^{2} - 9) - 5 = -(x - 3)^{2} + 4\textsf{.} The constant 44 is the maximum value of y.y\textsf{.}

Which is the completely factored form of 12x2+8x12x^{2} + 8x?

The greatest common factor of 12x212x^{2} and 8x8x is 4x.4x\textsf{.} Factoring gives 4x(3x+2)4x(3x + 2).

Which expression is equivalent to 49−x249 - x^{2}?

49−x2=72−x2=(7−x)(7+x)49 - x^{2} = 7^{2} - x^{2} = (7 - x)(7 + x).

Which expression is equivalent to 28zf+28z\dfrac{28z}{f} + 28z, where f>0f > 0?

Write 28z28z with denominator ff: 28zf+28zff=28z+28zff=28z(f+1)f\dfrac{28z}{f} + \dfrac{28zf}{f} = \dfrac{28z + 28zf}{f} = \dfrac{28z(f + 1)}{f}.

In the factorization x3−125=(x−5)(x2+5x+c)x^{3} - 125 = (x - 5)(x^{2} + 5x + c), what is cc?

Difference of cubes: x3−125=(x−5)(x2+5x+25)x^{3} - 125 = (x - 5)(x^{2} + 5x + 25), so c=52=25c = 5^{2} = 25.

Practice playeasy

Factor: x2−25x^{2} - 25.

x2−25x^{2} - 25 is a difference of squares: x2−52x^{2} - 5^{2}. So x2−25=(x+5)(x−5)x^{2} - 25 = (x + 5)(x - 5).

Practice playmedium

If 3x2−12x=93x^{2} - 12x = 9, what is the value of x2−4x?x^{2} - 4x\textsf{?}

Divide both sides by 33: x2−4x=3x^{2} - 4x = 3.
