Which factors can be multiplied together to make the trinomial 5x2 + 8x - 4? Check all that apply. (x + 1) (2x + 1) (x + 2) (5x + 1) (5x - 2) Mark this and return Save and Exit

(5x-2) and (x+2)

the factors are (5x-2) and (x+2)

Step-by-step explanation:

5x^2 + 8x - 4

first we multiply 5 and - 4 = - 20

product is - 20 and sum is + 8

find out two factors whose product is - 20 and add upto + 8

10 * (-2) = 20

10 + (-2) = 8

5x^2 + 10x-2x - 4

group the terms and factor out GCF

(5x^2 + 10x) + (-2x - 4)

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

(5x-2) (x+2)

the factors are (5x-2) and (x+2)
