Question

Plz guys i want complete solution

Answer 1

Answer:

Here is ur answer mate

${x}^{2} - 4x + 2 = 0$

Compare the eqution with

${ax}^{2} + bx + c$

1. a=1
2. b= -4
3. c=4

$\sqrt{ {b}^{2} } + \sqrt{2ac}$

=4+2=6

Like this u can find further Discriminant Hope it helps u

Mark this ans as brainlliest

Answer 2

General form of a quadratic equation = $x^{2} + ax + b$

where,

x is a variable, a is cofficient of x, and b is constant

Formula of discriminant = $b^{2} - 4ac$

a) D=8

b) D = $p^{2} - 8q$

c) D = -3

d) D = -16

e) D = 16 - 4α

f) D = 16, it is a perfect square.

Hope it helps!
