2x squared minus 4
The expression simplifies to: -7x-4
(2x - 1)(x + 4)
(4+x) (2x-3)
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
2x squared minus 4
(x2-7x+12)/(x2-2x-3)factor the numerator & denominator:(x-4)(x-3)/(x-3)(x-1)now reduce:(x-4)(x-3)/(x+1)(x-3)(x-4)/(x+1)
The expression simplifies to: -7x-4
(2x - 1)(x + 4)
(4+x) (2x-3)
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
2x2-9x+4 = (2x-1)(x-4) when factored
(x + 2)(x - 4)
(2x - 4)(2x + 3) The key is to look for all the factor pairs of 12.
(x+2)(x−4)
The factors are -1(2x + 1)(3x + 4)
