Question

Check whether the following are quadratic
equations :
(1)(x - 3)2 = x (2x - 5)​

Answer 1

Answer:

2x-6=2x^2-5x

2x^2-5x-2x+6

2x^2-7x+6

hence it is a quadratic equations

Answer 2

${(x - 3)2} = x(2x - 5)$

$2x-6= 2 {x}^{2} - 5x$

$2 {x}^{2}-5 x-2x+6 = 0$

$2{x}^{2}-7x+6= 0$

•°• it is a quadratic equation.
