Question

find the discriminant of 2X2 -5x+3=0 and write the nature of roots and find roots if exist​

Answer 1

Answer:

x=3/2 or 1

Step-by-step explanation:

Given 2x^2 - 5x + 3 = 0. This is of the form ax^2 + bx + c = 0 where a= 2, b = -5 and c= 3

Given equation can be written as 2x^2 - 5x = - 3

Multiply both sides by 4a i.e., by 8

16 x^2 - 40x = - 24

Add b^2 = 25 to both sides

16x^2 - 40x + 25 = -24 +25

(4x)^2 - 2.4x .5 + 5^2 = 1

(4x - 5)^2 = 1

4x - 5 = +1 or 4x - 5 = -1

4x= 6 or 4x = 4

x = 3/2 or 1
