The first steps in writing f(x) = 4x² + 48x + 10 in vertex form are shown.f(x) = 4(x² + 12x) + 10

= 36

What is the function written in vertex form?

Answers

Answer 1

Answer: Hello,

y=4x²+48x+10
==>y=4(x²+12x)+10
==>y=4(x²+2*6x+36)+10-4*36
==>y=4(x+6)²-134

But you are finding out A, not C, so you must rearrange the equation.

Asquared=Csquared-Bsquared
Asquared= 484-256
Asquared=228
A=Square root of 228
A=15 :)

Factor the following equation to solve for "x"; x^{2} - 8x - 20 = 0

Answers

x² - 8x - 20 = 0

Factor the left side:

(x + 2) (x - 10) = 0

That's a true statement if (x = -2) or if (x= 10), so those are your solutions.

x = -2
x = 10

By the way ... you don't factor an equation. You can only factor an expression.
