Answer:
6(x+2)(x-5)
Explanation:
This is factoring trinomials, so x^2+ bx+c. In order to this you need to find two integers whose product is c and whose sum is b. Rewrite the trinomial as x2 + rx + sx + c and then use grouping and the distributive property to factor the polynomial. The resulting factors will be (x + r) and (x + s).
