Given is :
The area of the rectangular patio is = 130 square feet
Let the width of the patio be = x feet
As length is 3 feet more than the width, so the length is = x+3 feet
Now area of rectangle is = length * width
This gives either x-10=0 or x+13=0
x-10=0 ; x=10
x+13=0 ; x=-13 (neglect this negative value)
So, the width of the patio is = 10 feet
Length = 10+3 = 13 feet
Answer:
Step-by-step explanation:
Factorise the numerator and denominator
x² - x - 6 = (x - 3)(x + 2)
x² + 2x - 15 = (x - 3)(x + 5)
Hence
=
Cancel the factor (x - 3) on the numerator/ denominator leaving
← equivalent expression
