Question

check wether x(x+2)- 3 = (x+4)x is quadratic equation.​

Answer 1

Step-by-step explanation:

x(x+2)-3 = (x+4)x

x^2 + 2x -3 = x^2 +4x

2x=-3

therefore it aint a quadratic equation

Answer 2

Answer:

x(x+2)- 3 = (x+4)x

or x²+ 2x - 3 = x² + 4x

or x²-x² + 2x - 4x -3 = 0

or 0 - 2x - 3 = 0

or -2x - 3 =0

we can prove this is a quadratic equation as format of quadratic equation is ax²+bx+ c = 0

over here; a = 0, b= -2, c = -3
