Question

what is the answer to x (x+8)=9​

Answer 1

Answer:

x=1 or x=−9

Step-by-step explanation:

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

x(x+8)=9

Step 1: Simplify both sides of the equation.

x2+8x=9

Step 2: Subtract 9 from both sides.

x2+8x−9=9−9

x2+8x−9=0

Step 3: Factor left side of equation.

(x−1)(x+9)=0

Step 4: Set factors equal to 0.

x−1=0 or x+9=0

x=1 or x=−9

Answer 2

Hey there!

(x + 8) = 9

➡️ x + 8 = 9

SUBTRACT 8 to BOTH SIDES

x + 8 - 8 = 9 - 8

CANCEL out: 8 - 8 because that gives you 0

KEEP: 9 - 8 because it helps solve for the x-value

x = 9 - 8

9 - 8 = x

9 - 8 = 1

Therefore your answer is: x = 1

Good luck on your assignment and enjoy your day!
