Answer 1

Heyy Buddy

Here's your Answer

Option A and Option C.

x^2 - 7x + 2 = 0

2x^2 + 10x + 1.

✔✔✔

Reason:-

Quadratic Equations is define as the equation involving the second Power (2) to the variable.

Here,

☆ X^2 - 7x + 2 =0 has power 2 on its variable.✔✔


☆ 7x^5 - x(x+2) =0 Has power 5 as its highest power. So, it isn't quadratic. ❌❌

☆ 2x(x+5)+1 =0

=> 2x^2 + 10x + 1 it also contain power 2 as its highest power. So, it is a quadratic. ✔✔

☆ 2x-1 =0

It contain power 1 as its highest power. So, it isn't the Quadri.❌❌❌

Answer 2

hay friend it is your answer

so,at first we get x^2 - 7x +2 , the highest value of it is 2 . so, it is quadratic

ii) 7x^5 +x (x + 2) =7^5+ x^2+2x here the highest value is 5 so it is not quadratic

iii) 2x(x+5 )+1=2x^2 +10x +1 ,it is quadratic

iv) 2x-1 is not quadratic
