Answer:
a) x=0, x=-10, x=11
Step-by-step explanation:
Just find the x- coordinates for when f(x) intersects g(x).
Answer:
x = ±
- 2
Step-by-step explanation:
x² + 4x = 4
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 4 + 4
(x + 2)² = 8 ( take square root of both sides )
x + 2 = ±
( subtract 2 from both sides )
x = ±
