Question

(x+3)^2-9=7 solve by square root

Answer 1

Step-by-step explanation:

${x}^{2} + 6x - 7$

Let's solve your equation step-by-step.

(x+3)2−9=7

Step 1: Simplify both sides of the equation.

x2+6x=7

Step 2: Subtract 7 from both sides.

x2+6x−7=7−7

x2+6x−7=0

Step 3: Factor left side of equation.

(x−1)(x+7)=0

Step 4: Set factors equal to 0.

x−1=0 or x+7=0

x=1 or x=−7

Answer:x=1 or x=−7
