Write p(x) = 21 + 24x + 6x2 in vertex form.

Citrus2011 [14]

<u>ANSWER</u>

$p(x)=-3+6(x+2)^2$

<u>EXPLANATION</u>

The given function is

$p(x)=21+24x+6x^2$

We make the coefficient of $x^2$ unity by factoring $6$ out of the last two terms to obtain;

$p(x)=21+6(4x+x^2)$

We now add and subtract half the coefficient of $x$ multiplied by a factor of 6 to obtain;

$p(x)=21-6(2)^2+6(2)^2+6(4x+x^2)$

We now factor 6 out of the last two terms to get;

$p(x)=21-6\times 4+6((2)^2+4x+x^2)$

$p(x)=21-24+6((2)^2+4x+x^2)$

The quadratic trinomial in the parenthesis is now a perfect square.

$p(x)=-3+6(x+2)^2$

Hence the vertex form of the polynomial is

$p(x)=6(x+2)^2-3$

a person walks 80 feet in 40 seconds. what equation represents this relationship. how many feet will the person walk in 10 secon

larisa [96]

Answer:

20 feet

Step-by-step explanation:

$\frac{80 feet}{40 seconds}$ = $\frac{x feet}{10 seconds}$

Simplify $\frac{80}{40}$

$\frac{80}{40}$ = $\frac{2}{1}$

Every 1 second, a person will walk 2 feet.

$\frac{x}{10}$ = $\frac{20}{10}$

X = 20 feet
