Question

9x(2x-5)-7(2x-5)-3x(5x-3)-8(5x-3)​

Answer 1

Step-by-step explanation:

(9x-7)(2x-5)-(3x-8)(5x-3)

[9x(2x-5)-7(2x-5)]-[3x(5x-3)-8(5x-3)]

[18x^2-45x-14x+35]-[15x^2-9x-40x+24]

3x^2+(-45-14+9+40)x+(35-24)

3x^2-10x+11

Answer 2

Answer:

3x²-90x+59

Step-by-step explanation:

9x(2x-5)-7(2x-5)-3x(5x-3)-8(5x-3)

=9x*2x-9x*5-7*2x+7*5-3x*5x+3x*3-8*5x+8*3

=18x²-45x-14x+35-15x²+9x-40x+24

=18x²-15x²-45x-14x+9x-40x+35+24

=3x²-90x+59
