-1
y = -9
y2-x2 = (y+x)(y-x)
(x + 4)(x + 1)
so x squared + 12 = 0 so xsquared = -12 which lands you in the realm of imaginary numbers. The square root of -12 is 2i root 3 where i is the imaginary sqrt of -1.

Dire.
The value of X after simplifying fully xsquared -16 3xsquared plus 10x -8 is either 2 or 4.
find factors of -3 (3 & -1 ) also add together to get 2 (for the 2x part) put x on both sides (x+3) (x-1) << because xsquared means x times x check it 3 times -1 = -3 3 times x = 3x -1 times x = -1x x times x = xsquared = xsquared + 2x -3 hope this helped =)
x times x x multiplied by itself
(x - 20)(x - 20)
x^3 - 121x
7
(x - 7)(x + 2)
That would depend on the value of 56 which has not been given.
y = -9
