THIS IS THE BEST ANSWER 👇

What factors can be multiplied together to make the trinomial 5×2 + 8x – 4? Check all that is in place.

(x + 1)

(2x + 1)

(x + 2)

(5x + 1)

(5x – 2)

Solution:

By multiplication (5x – 2) and (x + 2), the given trinomial is obtained as follows.
(5x – 2) * (x + 2) = (5x * x) + (5x * 2) – (2 * x) – (2 * 2)
= 5x ^ 2 + 10x – 2x – 4
= 5x ^ 2 + 8x – 4
