Question

Factor the trinomial completely 3x^2-5x-2

Answer 1

Answer:

(x − 2)×(3x+1)

Step-by-step explanation:

We can use this method:

$\begin{aligned}3 x^{2}-5 x-2 &=3 x^{2}-5 x-x+x-2 \\\\&=3 x^{2}-6 x+x-2 \\\\&=3 x \cdot(x-2)+(x-2) \\\\&=(x-2)(3 x+1)\end{aligned}$

All I did is Subtracting x then adding x which will not affect the result because  -x + x = 0
