Answer:

$\left(2x-1\right)\left(2x+5\right)$

Step-by-step explanation:

║Given info║:

Factor completely: $4x^2 +8x -5$

Solution~:

Breaking the expression~: $\left(4x^2-2x\right)+\left(10x-5\right)$

Factor out 2x from 4x² -2x : 2x(2x-1)

Factor out 5 from 10x - 5 : 5(2x - 1)

Put together: $=2x\left(2x-1\right)+5\left(2x-1\right)$

Factor out 2x - 1: $=\left(2x-1\right)\left(2x+5\right)$
