The area of a rectangle is found by multiplying the length by the width: a = lw. a certain rectangle has an area of x2 + 7x + 12. factor the trinomial to find the length and width of the rectangle.

x^2+7x+12 can be done by factoring as a process of ax^2+bx+c, whereas a is equal to 1.

First, we need to know 2 numbers that multiply to 12 and add to 7. In that case, that would be 6 and 2. And then finally write the variable x in the first parts of the parentheses, that would be: (x+6)(x+2).

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
