Answer 1

$\huge\boxed{\fcolorbox{green}{purple}{Answer}}$

x + 2)2 = 2x2

∴ x2 + 4x + 4 = 2x2

∴ 2x2 – x2 – 4x – 4 = 0

∴ x2 – 4x – 4 = 0

Here, x is the only variable and maximum index of the variable is 2.

a = 1, b = -4, c = —4 are real numbers and

a ≠ 0.

∴ The given equation is a quadratic equation.

Answer:

a-s

b-p

c-r

d-q
