Are you asking how to solve for or how to factorize it? Anyways, to solve for , you have:

3x² + 10x + 8where

;

a = 3;

b = 10;

c = 8

Quadratic formula is the following:

To factorize it, you can use the box method:

3x² + 10x + 8

What multiplied by what gives 24 (a*c or 8*3), and added up gives 10 (b)? Obviously, in this case, 6 and 4.

3x² + 6x + 4x + 8;

(3x²+6x) + (4x+8);

3x(x+2) + 4(x+2);

(3x+4)(x+2)
