(x + 2)(x - 4)
2(x - 7)(x - 1)
-4
It is impossible but if it were x squared plus 2x minus 15 the equation would be (x+5) (x-3) with x being equal to either -5 or 3. If the original problem was x squared minus 2x minus 15 the equation would be (x-5)(x+3) and x would be equal to either 5 or -3
The expression 2x squared minus x squared simplifies to x squared. This is because when subtracting like terms, you subtract the coefficients while keeping the variable and its exponent the same. In this case, 2x squared minus x squared leaves you with just x squared.
(x - 2)(2x + 3)
2x squared - 5x - 3 = (2x +1)(x -3)
(x + 2)(x - 4)
(x - 5)(x + 3)
(2x - 3)(x + 2)
x(3x - 2)
(x - 1)(2x - 9)
(x - 2)(2x + 7)
(2x-3)(x-1)
2(x + 7)(x - 7)
2(x^2 - 8)
(x - 2)(2x - 3)
