Question

if (2x-5) (x-3)= 2x^2 + x + a, then the value of a is??​

Answer 1

Answer:

2x(x-3)-5(x-3)

2x²-6x-5x+15

2x²-11x+15=2x²+x+a

2x²-11x+15-2x²-x-a=0

-12x+15-a=0

12x-15+a=0

12x=15+a

x=5+a/4

Answer 2

Answer:

Step-by-step explanation:

2x-5)(x+3)=2x²+x+a

2x²+6x-5x+15=2x²+x+a

then 2x² get cancel from both the sides

6x-5x+15=x+a

6x-5x+15-x=a

x-x+15=a

15=a

Hope it helps
