Hope it helpssssssss !!!!!
Answer:
f(x) = 8 (x + ¼)² − ½
Step-by-step explanation:
f(x) = 8x² + 4x
Divide both sides by 8.
1/8 f(x) = x² + 1/2 x
Take half of the second coefficient, square it, then add to both sides.
(½ / 2)² = (1/4)² = 1/16
1/8 f(x) + 1/16 = x² + 1/2 x + 1/6
Factor the perfect square.
1/8 f(x) + 1/16 = (x + 1/4)²
Multiply both sides by 8.
f(x) + 1/2 = 8 (x + 1/4)²
Subtract 1/2 from both sides.
f(x) = 8 (x + 1/4)² − 1/2
X(x - 6) = 4(x + 6)
x^2 - 6x = 4x + 24
x^2 - 6x - 4x - 24 = 0
x^2 - 10x - 24 = 0
(x - 12)(x + 2) = 0
x = -2, 12
The answer is: x = -2 and x = 12.
Answer:
5
Step-by-step explanation:
95+8=103
