Question

10x^2-15x+63/5x^2-25x+12 =2x+3/x-5
Please someone solve this
It is so urgent!!! ​

Answer 1

Answer:

Step-by-step explanation:

Answer:

x = 9

Step-by-step explanation:

10x²+15x+63/5x²-25x+12 = 2x+3/x-5

=> (10x²+15x+63)(x - 5) = (5x²-25x+12)(2x + 3)

=> 10x³ - 50x² + 15x² -75x + 63x - 315 = 10x³ + 15x² -50x² -75x + 24x + 36

=>  63x - 315 = 24x + 36

=> 39x = 351

=> 13x = 117

=> x = 9

putting x = 9

1008/192  = 21/4

Divin=ding numerator & denominator of LHS by 21

=> 21/4 = 21/4

Answer 2

Answer:

x=9

Step-by-step explanation

cross multiply (10x^2+15x+63) with (x-5)________ I

cross multiply (5x^2-25x+12) with(2x+3)________II

=> 10x^3 -50x^2 +15x^2 -75x +63x -315 = 10x^3 +15x^2 -50x^2 - 75x +24x +36

=> cut [(10x^3) (-50x^2) (15x^2) (-75x)]

=> 63x-315=24x+36

=> 63x-24x=315+36

=> 39x=351

=> divied (39x=351) with (3)

=> 13x=117

=> x=9
