Question

Rewrite the function by completing the square.

h(x)= x^2+3x-18

Answer 1

Answer:

Step-by-step explanation:

Simplifying

h(x) = x2 + 3x + -18

Multiply h * x

hx = x2 + 3x + -18

Reorder the terms:

hx = -18 + 3x + x2

Solving

hx = -18 + 3x + x2

Solving for variable 'h'.

Move all terms containing h to the left, all other terms to the right.

Divide each side by 'x'.

h = -18x-1 + 3 + x

Simplifying

h = -18x-1 + 3 + x

Reorder the terms:

h = 3 + -18x-1 + x
