(x - 8)(x - 6)
3x² - 22x - 16 = (3x + 2)(x - 8)
It is: (c-4)(c-8) when factored
x2 - 7x = 8 x2 - 7x - 8 = 0Now find two numbers that multiply to equal -8, and add to equal -7.(1) * (-8) = -8(1) + (-8) = -7(x+1)(x-8) = 0 This is the factored form of x2 - 7x = 8You can then solve the equation if necessary, and get:x = -1 or x = +8
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
