Question

check whether it is a quadratic equation =

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

*✧* Relevant Answer *✧*​

Answer 1

Answer:

Step by step answer

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

x(2x+1) - 3(2x+1)=x²+5x

2x²+x-6x-3=x²+5

2x²-x²-6x+x=5+3

x²-5x=8

x²-5x-8=0

Here in the equation

A=1 B= -5 C= -8

Here ax²+bx+c=0 where a≠0

Therefore the given equation is quadratic equation.
