Answer:


8x3+24x2+10x+30= 2[(4x^2+5)(x+3)]

Explanation:

Given


8x3+24x2+10x+30= 2(4x^3+12x^2+5x+15)


8x3+24x2+10x+30= 2[4x^2(x+3)+5(x+3)]

Required

The complete factored form

We have:


8x3+24x2+10x+30= 2[4x^2(x+3)+5(x+3)]

Factor out x + 3


8x3+24x2+10x+30= 2[(4x^2+5)(x+3)]

The above represents the completely factored form
