Question

1. Factor 3h2 - 11h - 42 completely.

Answer 1

3h² - 11h - 42 = (3x+7)(x−6)

Explanation:

We need to find factors of 3h² - 11h - 42. It is a quadratic equation.

We search two numbers such that their product is 42 and sum is 11. So,

3h² - 11h - 42 = 3h² -18x +7x -42

= (3x+7)(x−6)

So, the required factors are (3x+7)(x−6).
