Question

algebra solve the following​

Answer 1

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
