Answer :
Solution:
Note that:
- Length of court = (6x² + 20x)
- Length of court = 2x(Width of court)
Divide the length of the court by 2x to find the width of the court.
- Width of court = (6x² + 20x)/2x
- => Width of court = 6x²/2x + 20x/2x
- => Width of court = 3x + 10
[tex]\\ \rm\hookrightarrow 6x^2+20x=2x[/tex]
[tex]\\ \rm\hookrightarrow 6x^2=-18x[/tex]
[tex]\\ \rm\hookrightarrow x^2=-3x[/tex]
[tex]\\ \rm\hookrightarrow x=-3[/tex]
