9x2-9x-10 = (3x+2)(3x-5) when factored
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
With the help of the quadratic equation formula
(9x + 8)(9x - 8)
x = -2/3,7/6
x2 + 9x2 = 10x2
9x2-9x-10 = (3x+2)(3x-5) when factored
x2-9x can be factored by taking x out of each term x(x-9)
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.
"10x - x" is basically 10 x's minus one x. The answer is 10 minus 1, but in terms of x. Since 10 minus 1 is 9, the answer is 9x.
5x2 + 9x + 13 has no real factors.
10x = 9x -25 10x -9x = -25 x = -25
With the help of the quadratic equation formula
That factors to 3x(3x - 1)
(9x + 8)(9x - 8)
x = -2/3,7/6
