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.
