Answer 1

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 2

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
