How the Georgia Milestones reports it

Georgia Milestones is Georgia’s own statewide assessment system, aligned to Georgia’s state-adopted content standards rather than a shared national test framework. The official page says it measures knowledge and skills in the state-adopted standards for mathematics across grades 3 through high school ([Georgia Department of Education](https://gadoe.org/assessment-accountability/georgia-milestones/)).

Which is the completely factored form of $16x^{3} + 24x^{2} - 8x$ ?

The greatest common factor of $16x^{3}$ , $24x^{2}$ , and $8x$ is $8x\textsf{.}$ Factoring gives $8x(2x^{2} + 3x - 1)$ .

Which expression is equivalent to $25x^{2} - 36$ ?

$25x^{2} - 36 = (5x)^{2} - 6^{2} = (5x - 6)(5x + 6)$ .

Which expression is equivalent to $\dfrac{35v}{k} + 70v$ , where $k > 0$ ?

Write $70v$ with denominator $k$ : $\dfrac{35v}{k} + \dfrac{70vk}{k} = \dfrac{35v + 70vk}{k} = \dfrac{35v(1 + 2k)}{k}$ .

Which expression is equivalent to $x^2 - 6x + 8$ ?

Find two numbers with product $8$ and sum $-6$ : $-2$ and $-4$ . So $x^2 - 6x + 8 = (x-2)(x-4)$ .

$x^{3} + 27 = (x + 3)(x^{2} - 3x + c)$ . What is $c$ ?

Sum of cubes: $x^{3} + 27 = (x + 3)(x^{2} - 3x + 9)$ , so $c = 3^{2} = 9$ .

Practice playeasy

Factor: $x^{2} - x - 12$ .

Two numbers that multiply to $-12$ and add to $-1$ are $3$ and $-4$ . So $x^{2} - x - 12 = (x + 3)(x - 4)$ .

Practice playmedium

Solve for the value of $x^{2} + 3x$ if $3x^{2} + 9x - 12 = 0$ .

Factoring out the GCF $3$ gives $3(x^{2} + 3x - 4) = 0$ . Since $3(0) = 0$ , $x^{2} + 3x - 4 = 0$ . Isolate the desired expression by adding $4$ to both sides: $x^{2} + 3x = 4$ .
