2x2-9x+4 = (2x-1)(x-4) when factored
Assuming it's a plus sign, that factors to (2x + 1)(x + 4)
9x2 - 18x + 99(x2 - 2x + 1)==========
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
2x2+9x+9 = (2x+3)(x+3) when factored
6x3 + 9x2 - 2x2 - 3x Before any grouping, take out the common factor, x, to give x*(6x2 + 9x - 2x - 3) = x*[3x*(2x + 3) - 1*(2x + 3)] = x*(2x + 3)*(3x - 1)
3x^(2) +9x - 2x -6 Collect 'like terms'. Hence 3x^(2) + 7x - 6 Next write down all the factors of '3' and '6' Hence 3 ; 1' & 3' 6 ; 1,6 ; 2,3. From these pairs of number we select a pair from each coefficient, that add/multiply to '7' . Hence (3' x 3 ) & (1' x 2) ; NB 'dashes' (') to indicate source of numbers. Write up brackets (3x 2)(x 3) -2)(x + 3) Next we notice that the '6' is negative, so the two signs are different (+/-) The '7x' is positive , so the larger number takes the positive sign . Hence (3x - 2)(x + 3)
Assuming it's a plus sign, that factors to (2x + 1)(x + 4)
9x2 - 18x + 99(x2 - 2x + 1)==========
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
(2x+3)(x+3)
2x2+9x+9 = (2x+3)(x+3) when factored
(2x+3)(x+3)
6x3 + 9x2 - 2x2 - 3x Before any grouping, take out the common factor, x, to give x*(6x2 + 9x - 2x - 3) = x*[3x*(2x + 3) - 1*(2x + 3)] = x*(2x + 3)*(3x - 1)
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
If you mean: 2x^2 +9x +7 then it is (2x+7)(x+1) when factored
Use the quadratic formula. x = -4.265564 or -0.234436
