3 out of the following equations.
quadratic equation ?
KAY X?+42-11+x2
<c) 5x²-90
<B> x=4x.
<D> 2x-x² = x²+5​

Answer 1

Answer:

b. x=4x is not the quadratic equation because a quadratic equation must have degree of 2 to be called as quadratic, hence it is not a quadratic equation

Answer 2

Answer:

<B> x=4x.

Step-by-step explanation:

<B> x=4x. is not a quadratic equation because here, the highest power of variable is 1.

Hence it is not of the form (ax²+bx+c=0)

But , we know quadratic equations area of the form (ax²+bx+c=0)
