4 x 2 means you are adding 4 two times, 4 x 2 = 4 + 4 = 8
4 ^ 2 (4 to the 2 power) means you are muliplying by 4 two times, 4 x 4 = 4 + 4 + 4 + 4 = 16

ANSWER: -4X2 -8X-4x (x+2)= (-4x * x) + (-4x*2)= -4X2 -8X
-4x2 + 11x - 6 factors to: (-4x + 3) (x - 2)
6x2-4x2+3 = 0 2x2 + 3 = 0 2x2 = -3 x2 = -3 / 2 this equation has imaginary roots x = +sqaureroot (3/2)i , -sqaureroot (3/2)i where i = complex variable
To do a sum like 2 to the power of 5, this is how you would work thisquestion out: 2x2 5 times = 1x2=2 2x2=4 4x2=8 8x2=16 16x2=32 if you don't understand, comment and i will help!
I assume you mean factors for 4x2+10x+6.(2x+3)(2x+2).
