Rewrite each expression by completing the square q^2+12q+32

julia-pushkina [17]

The given expression can be written as $q^{2} +12q+32$ = (q+8)(q+4).

Step-by-step explanation:

Given,

$q^{2} +12q+32$

To make it a complete square.

Formula

(a+b)² = $a^{2} +2ab+b^{2}$

$a^{2} -b^{2} = (a+b)(a-b)$

Now,

$q^{2} +12q+32$

= $q^{2} +2.q.6+6^{2} -6^{2} +32$

= (q+6)²-36+32

= (q+6)²-4

= (q+6)²-2²

= (q+6+2)(q+6-2)

= (q+8)(q+4)

The owner of a video game store creates the expression −2x2 + 24x + 174 to represent the store's weekly profit in dollars, where

Semmy [17]

Answer:

$-2(x-6)^2+246$ , x = $6

Step-by-step explanation:

The expression $-2x^2+24x+174$ to represent the store's weekly profit in dollars, where x represents the price of a new video game.

Let $f(x)=-2x^2+24x+174$

We need to rewrite this quadratic function in the vertex form.

$f(x)=-2(x^2-12x)+174$

$f(x)=-2(x^2-12x+36)--2(36)+174$

$f(x)=-2(x^2-12x+36)+72+174$

$f(x)=-2(x-6)^2+246$

The equivalent expression that reveals the video game price that produces the highest weekly profit is $-2(x-6)^2+246$

and the price is $6
