Step-by-step explanation:

1 X2+X2+=2

Answer 2

Pls mark it brainliest

Answer:

A] x² + x² = 2

- - > 2x² = 2

- - > 2x² - 2 = 0

B] P ( p - 1) = 0

- - > p² - p = 0

C] x² = 6 + x² - x

- - > x² - x² + x - 6 = 0

- - > x - 6 = 0

D] x² + 1/x = 5

- - > x² + 1 = 5x

- - > x² - 5x + 1 = 0

Therefore option a, b and d are in the form of quadratic equation

Because they are in the form of ax² + bx + c where a ≠ 0, b and c can also be 0,1,2.....
