Question

Find the zeroes v2+4root3-15

Answer 1

heya..!!!


i think some typing mistake


right questions is like that:+

v² + 4√3v - 15

=> v² + 5√3v - √3v - 15

=> v(v + 5√3) - √3(v + 5√3)

=> (v - √3)(v + 5√3)

hope it's help you

Answer 2

Hi ,

Let p( v ) = v² + 4√3v - 15,

To find the zeroes of p( v ) , we have

Take p( v ) = 0

Therefore ,

v² + 4√3v -15 = 0

v² + 5√3v - √3v - 15 = 0

v² + 5√3v - √3v - 5√3 × √3 = 0

v( v + 5√3 ) - √3 ( v + 5√3 ) = 0

( v + 5√3 ) ( v - √3 ) = 0

v + 5√3 = 0 or v - √3 = 0

v = - 5√3 or v = √3

Therefore ,

-5√3 , √3 are Zeroes of p( v )

I hope this helps you.
