Answer:
x = 4 or x = -10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x^{2}+6x+9=49
Step 2: Subtract 49 from both sides.
x^{2}+6x+9−49=49− 49
x^{2}+6x−40=0
Step 3: Factor left side of equation.
(x−4)(x+10)= 0
Step 4: Set factors equal to 0.
x−4= 0 or x+10=0
x=4 or x=−10
Answer:A and C
Step-by-step explanation:
(x+3)^2=49
Take the square root of both sides
√((x+3)^2)=±√(49)
x+3=±7
collect like terms
x=-3±7
x=-3+7 or x=-3-7
x=4 or x=-10
