Answer 2

Step-by-step explanation:

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

(3x+5)(3x+5)=1

Step 1: Simplify both sides of the equation.

9x2+30x+25=1

Step 2: Subtract 1 from both sides.

9x2+30x+25−1=1−1

9x2+30x+24=0

Step 3: Factor left side of equation.

3(3x+4)(x+2)=0

Step 4: Set factors equal to 0.

3x+4=0 or x+2=0

x=−4/3 or x=−2

Answer:

x=−4/3 or x=−2
