What is the value of this quadratic function. 4x^2+88x

Mathematics
1 answer:
nydimaria [60]3 years ago
5 0

Answer:

x = 0 or x = -22

Step-by-step explanation by completing the square:

Solve for x:

4 x^2 + 88 x = 0

Divide both sides by 4:

x^2 + 22 x = 0

Add 121 to both sides:

x^2 + 22 x + 121 = 121

Write the left hand side as a square:

(x + 11)^2 = 121

Take the square root of both sides:

x + 11 = 11 or x + 11 = -11

Subtract 11 from both sides:

x = 0 or x + 11 = -11

Subtract 11 from both sides:

Answer:  x = 0 or x = -22
