Question

f(x)=2x^2+16x-7

Answer 1

\[-b \pm \sqrt{b ^{2}-4ac}/2a\]

Answer 2

a=2,b=16 and c=-7
plug in the values

Answer 3

the formual is f(x)= a(x-h)^2+k

Answer 4

i thought uhad to find the roots..

Answer 5

trying to find the missing values

Answer 6

f(x)=2x^2+16x-7
f(x)=2(x^2+8x)-7
f(x)=2(x^2+8x+16-16)-7
(x)=2(x^2+8x+16)-32-7
=2(x+4)^2-39
=2(x-(-4))^2-39
