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)
Solution:
The quadratic trinomial given is 5x2 + 8x - 4
By splitting up the middle term
= 5x2 + 10x - 2x - 4
By grouping the terms and factoring the trinomial
= 5x(x + 2) - 2(x + 2)
= (5x - 2)(x + 2)
Therefore, the factors that can be multiplied are (5x - 2)(x + 2).
Which factors can be multiplied together to make the trinomial 5x2 + 8x - 4? Check all that apply.
Summary:
The factors that can be multiplied together to make the trinomial 5x2 + 8x - 4 is (5x - 2)(x + 2).
