Question

simplify it (5x square+3x -7) (x-1 ) -(2x square +3x -4) (2x -3)​

Answer 1

Answer:

x³-2x²+7x+2

Step-by-step explanation:

(5x²+3x-7) (x-1) - (2x²+3x-4) (2x-3)

[x(5x²+3x-7) -1(5x²+3x-7)] - [2x(2x²+3x-4) -3 (2x²+3x-4)]

[5x³+3x²-7x-5x²-3x+14] - [4x³+6x²-8x-6x²-9x+12]

[5x³+3x²-7x-5x²-3x+14] -4x³-6x²+8x+6x²+9x-12

(5-4)x³ + (3-5-6+6) x² + (-7-3+8+9)x + (14-12)

x³-2x²+7x+2
