Question

(x-3)(2x+1)=x(x+5) check whether it is a quadratic equation

Answer 1

Answer:

hope u the answer help u

Step-by-step explanation:

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

2x²-6x+x-3=x²+5x

2x²-6x+x-3-x²-5x=0

x²-10x-3=0

its form quadratic equation

Answer 2

Answer:

$(x - 3)(2x + 1) = x(x + 5) \\ It \: \: is \: \: a \: \: Quadratic \: \: Equation$

Step-by-step explanation:

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