Radda [10]

Answer:

$(x-2)^2-30$

Step-by-step explanation:

use the form $ax^2+bx+c$ to find the values of a, b, and c.

$a=1, b= -4, c = -26$

consider the vertex form of a parabola

$a(x+d)^2+e$

substitute the values of a and b into the formula $d=\frac{b}{2a}$

$d=\frac{4}{2(1)}$

simplify the right side.

find the value of e using the formula $e=c-\frac{b^2}{4a}$

$e=30$
