Question

(5x-3)(x+4)-(2x+5)(3x-4)

Answer 1

Multiply (-3 + 5x) * (-2 + x)
(-3(-2 + x) + 5x * (-2 + x))(5 + 2x) + -1(3x + -2)(2x + -5)(x + -4) = 0
((-2 * -3 + x * -3) + 5x * (-2 + x))(5 + 2x) + -1(3x + -2)(2x + -5)(x + -4) = 0
((6 + -3x) + 5x * (-2 + x))(5 + 2x) + -1(3x + -2)(2x + -5)(x + -4) = 0
(6 + -3x + (-2 * 5x + x * 5x))(5 + 2x) + -1(3x + -2)(2x + -5)(x + -4) = 0
(6 + -3x + (-10x + 5x2))(5 + 2x) + -1(3x + -2)(2x + -5)(x + -4) = 0

Answer 2

Q: (5x-3)(x+4)-(2x+5)(3x-4)

= 5x(x+4)-3(x+4)-2x(3x-4)+5(3x-4)
= 5x²+20x-3x-12-6x²+8x+15x-20
= - x²+40x-32 ans.
