Question

Find the root of the equation 5x^2root15x+3=0

Answer 1

Answer:

You must know it is a quadratic equation

Step-by-step explanation:

5x^2 √15x +3=0

COMPARING THE EQUATION WITH ax^2 +bx+c,

we get, a=5 ,b=√15 ,c=3

∆=b^2 - 4ac

=(√15)^2 - 4×5×3

= - 45

By formula method,

x= -b ± √b^2-4ac

2a

x= -√15± √-45

2×5

x= -√15 ± 3√5i .......(√-1 =I)

10

so,

x= -√15+3√5i or x= -√15-3√5i

10 10
