A rectangular garden has a length of 2m + 13 feet and a width of 5m feet.

A = Lw (Area equal length times width)

A = 48 (the garden's area is 48 ft2)

L = w + 2

We have values for our variables, so let's plug them in:

48 = w(w + 2)

Distribute:

48 = w2 + 2w

Subtract 48 from both sides:

0 = w2 + 2w - 48

AS you can see, we now have a quadratic. From here we need:

m + n = 2 and

m * n = -48

When we break up the quadratic into (w + m)(w + n)

48 is an even number divisible by 3, so it'll be also be divisible by 6:

48 / 6 = 8

8 + (-6) = 2

8 * -6 = -48, so:

0 = (w + 8)(w - 6) →→ 0 = w + 8, or 0 = w - 6

w = -8 or 6
