Question

Check whether the following are quadratic equations or not
1) 2(x-1) ²=4x²-2x+1
2) 2x-x²=x²+5
3) (√2x+√3) ²+x²=3x²-5x
4) (x²+2x²) =x⁴+3+4x³
5) 3x²-2√x+8=0​

Answer 1

Answer:

1st=yes it is quadratic

2nd= yes it is quadratic

3rd= it is quadratic

4rth = it is not quadratic

5th=it is notquadratic

Answer 2

Step-by-step explanation:

We know that if the equations are of the form ax sq + bx+c then they are known as quadratic equations. so, solve the following equations and if they are of the form that I have told above, then that that will be quadratic equations
