Question

Factor the trinomial below*1 point3x² + 13x - 10(3x + 2)(x - 5)(3x + 5) (x - 2)Option 1Option 2هما(3x − 2)(x + 5)(3x - 5)(x + 2)Option 3Option 4

Answer 1

The given trinomial is a quadratic equation. It is expressed as

3x^2 + 13x - 10

We would apply the method of factorisation. To do this, we would find two terms such that

their sum or difference is 13x and their product is - 30x^2. The terms are 15x and - 2x. Thus, we have

3x^2 + 15x - 2x - 10

3x(x + 5) - 2(x + 5)

(3x - 2)(x + 5)

The correct option is option 3
