What the test measures

Seeing Structure in Expressions skills

  1. Interpret the structure of expressions

  2. Write expressions in equivalent forms to solve problems

  3. Perform arithmetic operations on polynomials

Standards basis

Common Core State Standards for Mathematics (CCSS-M) / PARCC Model Content Frameworks — national

How the PARCC reports it

PARCC was a multistate assessment system built around the Common Core-era PARCC mathematics model content frameworks rather than a separate proprietary standards set. Its math structure is organized by grade/course and aligned to CCSS-M content categories and model content frameworks.

Which is the completely factored form of 14x2+21x14x^{2} + 21x?

The greatest common factor of 14x214x^{2} and 21x21x is 7x.7x\textsf{.} Factoring gives 7x(2x+3)7x(2x + 3).

Which expression is equivalent to x264x^{2} - 64?

x264=x282=(x8)(x+8)x^{2} - 64 = x^{2} - 8^{2} = (x - 8)(x + 8).

Which expression is equivalent to 15pr+15p\dfrac{15p}{r} + 15p, where r>0r > 0?

Write 15p15p with denominator rr: 15pr+15prr=15p+15prr=15p(r+1)r\dfrac{15p}{r} + \dfrac{15pr}{r} = \dfrac{15p + 15pr}{r} = \dfrac{15p(r + 1)}{r}.

If x214x+49=(xa)2x^{2} - 14x + 49 = (x - a)^{2} with a>0a > 0, find aa.

Half of 1414 is 77 and 72=497^{2} = 49, so x214x+49=(x7)2x^{2} - 14x + 49 = (x - 7)^{2} and a=7a = 7.

Factor: x23x+2x^{2} - 3x + 2.

Two numbers that multiply to 22 and add to 3-3 are 1-1 and 2-2. So x23x+2=(x1)(x2)x^{2} - 3x + 2 = (x - 1)(x - 2).

The equation 5x220x+15=05x^{2} - 20x + 15 = 0 is true. What is x24x?x^{2} - 4x\textsf{?}

Factoring out the GCF 55 gives 5(x24x+3)=05(x^{2} - 4x + 3) = 0. Since 5(0)=05(0) = 0, x24x+3=0x^{2} - 4x + 3 = 0. Isolate the desired expression by subtracting 33 from both sides: x24x=3x^{2} - 4x = -3.

Practice playeasy

Which expression is equivalent to x2+7x+12x^2 + 7x + 12?

Find two numbers with product 1212 and sum 77: 33 and 44. So x2+7x+12=(x+3)(x+4)x^2 + 7x + 12 = (x+3)(x+4).

Practice playeasy

Which expression is equivalent to (7p)(pq)(2q)?(7p)(pq)(2q)\textsf{?}

Multiply the coefficients: 712=14.7 \cdot 1 \cdot 2 = 14\textsf{.} Add the exponents on pp and on qq: p1+1q1+1=p2q2.p^{1+1} q^{1+1} = p^{2} q^{2}\textsf{.} So the product is 14p2q2.14p^{2}q^{2}\textsf{.}
