Your answer would be 15 m if i’m doing it right
The correct quadratic equation;
x2+7x-2=0
Working
Assuming the frame has a uniform thickness;
Then length of mirror and frame is 3+x and width 2+x
The area of mirror and frame area;
A=L*W
8=(3+x)(2+x)
8=(6+5x+x2)
Taking 8 to the Right hand side, we have:
x2+5x-2 =0

Answer:
x=−14
Step-by-step explanation:
Step 1: Subtract x from both sides.
3x+20−x=x−8−x
2x+20=−8
Step 2: Subtract 20 from both sides.
2x+20−20=−8−20
2x=−28
Step 3: Divide both sides by 2.
2x
2
=
−28
