Answer:

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax2 + bx + c where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where ‘a’ is called the leading coefficient and ‘c’ is called the absolute term of f (x). The values of x satisfying the quadratic equation are the roots of the quadratic equation (α,β).

The quadratic equation will always have two roots. The nature of roots may be either real or imaginary.

hope this helps u don't forget to follow me ( ╹▽╹ )

Discriminant of the equation 2x² - 7x + p = 0 is 33

The value for p can be calculated as

Here a = 2 ; b = -7 ; c = p

•°• b2 - 4ac = (-7)² - 4 × 2 × p

= 49 - 8p .......(1)

But, b² - 4ac is 33 .....(2)

From 1 and 2

49 - 8p = 33

8p = 16

p = 16/8

p = 2
