By factorizing, we have

x^2 + 5xy - 6y^2 = (x - y) (x + 6y) = 0

so that

x - y = 0 \implies \boxed{y = x}

or

x + 6y = 0 \implies \boxed{y = -\dfrac x6}

The length of a rectangle is 5 more than the width. The area is 126 square feet. Find the length and width of the rectangle.
solmaris [256]

The length of the rectangle is 14 feet and the width of the rectangle is 9 feet.

The length of a rectangle is 5 more than the width. The area is 126 square feet.

We need to find the length and width of the rectangle.

<h3>What is the area of a rectangle?</h3>

The area of a rectangle is calculated by multiplying the rectangle's length by its width.

Let the width of the rectangle be x, then the length of the rectangle be x+5.

We know that the area of the rectangle = Length×Width

Now, the area of the rectangle = (x+5)×x=126 square feet.

⇒x^{2}+5x-126=0

⇒x^{2}+14x-9x-126=0

⇒x(x+14)-9(x+14)=0

⇒x=-14, x=9.

Since length cannot be a negative integer.

So, Width=9 feet and Length=9+5=14 feet.

Hence, the length of the rectangle is 14 feet and the width of the rectangle is 9 feet.
