Question

Simplify completely x^2 + 12x +35

________________
3x + 15 ...?

Answer 1

Answer: x + 7/ 3

Assuming the said quantity is divided by 3x+15 as a denominator in fraction form.

After dividing, the simplest form, x + 7/ 3, can be found after dividing both the numerators and the denominators by the smallest common factor.

Proof of validity is shown below.

Answer 2

The numerator will be, x2+12x+35=(x+7)(x+5)
The denominator would be,3x+15=3(x+5)
so you will have this equation.(x+7)(x+5)/3(x+5)
You can cancel out the (x+5) terms on the bottom and top and you end up with:(x+7)/3
