Answer:
1) (x+4)2 =49
Step-by-step explanation:
x^2+8x-33 = 0 Factor this equation
(x + 11)(x - 3) = 0 Set each equation equal to 0
x = -11 and 3
Test the first equation to see if it has the same solution
(x+4)2 = 49 Simplify the parentheses
(x+4)(x+4) = 49 FOIL the equation
x^2 + 8x + 16 = 49 Subtract 49 from both sides
x^2 + 8x - 33 = 0 This is the correct solution.
