Question

solve x2-2x+3=0 by quadratic equations​

Answer 1

Answer:

what is quadratic equations, I don't know about this

Answer 2

Answer:

Given :-

• Quadratic equation : x²-2x-3=0

To Find :-

• Discriminant

Solution :-

• We know that,

→ Discriminant = b² - 4ac

For the given equation :-

a = 1

b = -2

c = -3

Substituting the values :-

D = b² - 4ac

D= (-2) ² - 4 × 1× ( -3)

D = 4 + 12

D = 16

Value of Discriminant = 16
