Solution :
Let
p(x ) = √3x² + 10x + 7√3
Take p( x ) = 0
=> √3x² + 10x + 7√3 = 0
Splitting the middle term , we get
=> √3x² + 3x + 7x + 7√3 = 0
=> √3x² + (√3×√3 )x + 7x + 7√3 = 0
=> √3x( x + √3 ) + 7( x + √3 ) = 0
=> ( x + √3 )( √3x + 7 ) = 0
=> x + √3 = 0 or √3x + 7 = 0
=> x = -√3 or x = -7/√3
Therefore ,
-√3 , -7/√3 are zeroes of p(x).
