Answer:
x=9
Step-by-step explanation:
(x-5)(10x^2 + 15x + 63)= (2x+3)(5x^2- 25x + 12)
x(10x^2 + 15x + 63)-5(10x^2 + 15x + 63)=2x(5x^2 - 25x + 12)+3(5x^2 - 25x + 12)
10x^3+ 15x^2 +63x - 50x^2 - 75x - 315 = 10x^3 - 50x^2 + 24x + 15x^2 - 75x + 36
63x - 315 = 24x + 36
63x-24x = 36 + 315
39x = 351
x= 351/39
x= 9
