Question

check wheather the equation in quadratic or not
x2+3x+1=(x-1)2​

Answer 1

Answer:

No it is not a quadratic equation

Step-by-step explanation:

x²+3x+1=(x-1)²

x²+3x+1=x²-1²+2[ x(-1) ]

x²+3x+1=x²-1-2x

x²+3x+1=x²-2x-1

3x+2x+1+1=0

5x+2=0

any quadratic equation is equal to zero so it is not quadratic equation

LHS≠RHS

THEREFORE it is not a quadratic equation
