Can someone answer this quadratic?

Question

The question is:
5x(2x-3)=7(3-2x)

Answer 1

given equation is 5x(2x-3)=7(3-2x)

multiplication the equation

10x^2 - 15x = 21 - 14x------------------(1)

adding the 14x bothside equation (1)

10x^2 - 15x + 14x = 21

10x^2 - x =21 ------------------(2)

subtract the  21 bothside equation (2)

10x^2 -x  -21 =0

the quadratic equation is  10x^2 -x  -21 =0
