Question

check whether the following are quadratic equations:x(2x+3) =x2+1​

Answer 1

Answer:

yes...

Step-by-step explanation:

2x² + 3x = 2x + 1

2x² + 3x-2x - 1=0

2x²+x-1=0

Answer 2

Step-by-step explanation:

X(2x+3) = x²+1

2x²+3x = x²+1

2x²-x²+3x-1 = 0

X²+3x-1 = 0

It is the form of ax²+bx+c = 0

Where a = 1, b = 3 and c = - 1

Hence it is a quadratic equation.

Hope it helps you.
