3x2 - 7x + 2
= 3x2 - 6x - x + 2
= 3x(x - 2) - 1(x - 2)
= (3x - 1)(x - 2)
So x = 1/3 or x = 2

How do you factor 4x squared plus 4x -1?
Given 4x2+4x-1 Using the formula for the roots of quadratic equation, (-b +/-./b2-4ac)/2a the roots for the above will be (-4+/-4./2)/8 = (-1+/-./2)/2 Hence the two roots are (-1+./2)/2 and (-1-./2)/2 As the roots are irrational, there is no possibility of getting factors.
3x2 plus 8x plus 4 has two complex roots?
3x^2 + 8x + 4 = (x+2) (3x+2) x = -2 x = -2/3 So there are no complex roots, they are real. You can test this by b^2 - 4ac if greater than 0, it is real if equal, there will be 2 identical roots. if less than 0 you get imaginary roots.
