Step-by-step explanation:

<u><em>║Given info║:</em></u>

<em>Factor completely: </em> $4x^2 +8x -5$

<u><em>Solution~:</em></u>

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

<em>Factor out 2x from 4x² -2x : 2x(2x-1)</em>

<em>Factor out 5 from 10x - 5 : 5(2x - 1)</em>

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

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