Question

If 5x^2 + 8x + 4 = 2x^2 + 4x + 6 , Find the nature of the root. Plz Solve

Answer 1

Step-by-step explanation:

5x^2 + 8x +4 = 2x^2 +4x +6

5x^2 - 2x^2 +8x - 4x +4 - 6 = 0

3x^2 + 4x - 2 = 0

a= 3

b= 4

c= -2

D= b^2 - 4ac

D= (4)^2 - 4 (3)(-2)

D= 16-(-24)

D= 16+24

D= 40

D>0

So the equation has real roots
