Question

Write 4x2 + 16x - 9 in vertex form. Write 5x2 - 10x + 4 in vertex form.

Answer 1

Hi king,

Write
`4x^(2) + 16x - 9` in vertex form:

f(x)=
`4x^(2) + 16x - 9`

f(x)=
`4(x+2)^(2) -25`

Write
`5x^(2) - 10x + 4` in vertex form:

g(x)=
`5x^(2) - 10x + 4`

g(x)=
`5(x-1)^(2) -1`

Have a great day.
