Question

(x-3)(2x+1)=x(x+5) check ot is quardrati​

Answer 1

Answer:

$(x - 3)(2x + 1) = x(x + 5) \\ 2{x}^{2} + x - 6x - 3 = {x}^{2} + 5x \\ {x}^{2} - 10x - 3 = 0$

therefore it's a quadratic equation

Answer 2

Step-by-step explanation:

(x-3) (2x+1) = x(x+5)

2x^2+x-6x-3 = x^2+5x

2x^2 - 5x-3 = x^2+5x

2x^2-x^2 - 5x-5x = 3

x^2 - 10x = 3

HENCE PROVED THAT IT'S A QUADRATIC EQUATION.
