Question

b. 2x^2-13x + 15_solve polynomial by factoring.

Answer 1

We have the following quadratic expression,

$2x^2-13x+15$

we can rewrite this expression as follows:

$2(x^2-\frac{13}{2}+\frac{15}{2})$

The terms into the parenthesis can be written as

$x^2-\frac{13}{2}+\frac{15}{2}=(x-5)(x-\frac{3}{2})$

Therefore, the answer is

$2x^2-13x+15=2(x-5)(x-\frac{3}{2})$
