That's going to depend on the value of 'x'. But no matter what 'x' is, (x2-100) will be equal to the product of (ten more than 'x') and (ten less than 'x').
x = ? 42 = x squared minus x
it is equal to +x
(x - 5)(x + 4)
x - 3

8x2-10x-3 = (2x-3)(4x+1) when factored

9 - IX The Roman numeral for nine is "IX". The "X" stands for ten and the "I" stands for minus one. Ten minus one is nine. IX or VIIII.
Factor it. (x - 8)(x - 2) x = 2, 8
Solve using the quadratic formula
Seven (7)
X/[5 - (-10)] = 6 x/-15 = 6 x = - 90
It can be solved by using the quadratic equation formula.
One pair, 10z and -4z, since like terms are only terms that contain the same variable(s) with the same exponent.
