(x + 12)(x - 3)
In one bracket, write 16 times the square root of 2 minus 3x. In the other one, write 16 times the square root of 2 plus 3x.
it is a combination of perfect squares the square of 9x is squared is +/- 3x, and the square of 4 is +/- 2 so the answer is (3x+2)(3x-2) which is 9xsquared-6x+6x-4 =9xsquared-4
(2x+3)(x+3)
3(x2 + 3x + 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.
9x2-9x-10 = (3x+2)(3x-5) when factored
x2-9x can be factored by taking x out of each term x(x-9)
5x2 + 9x + 13 has no real factors.
With the help of the quadratic equation formula
That factors to 3x(3x - 1)
(9x + 8)(9x - 8)
x = -2/3,7/6
(3x + 8)(3x - 8)
It is a difference of squares. 9x^2-49=(3x+7)(3x-7)
2x2-9x+4 = (2x-1)(x-4) when factored
