Question

find the product of 3x^2-24

Answer 1

Answer:

I think so that the question is incomplete or not properly framed

Then too we can deduce the value of 'x' by the factor theorem

   x  =  +√8 , -√8

Explanation:

3x^2 - 24 ........ given polynomial

By using factor theorem,

3x^2 - 24 = 0

therefore, x^2 - 8 = 0 ..... dividing LHS and RHS by 3

                 x^2 = 8

therefore, x = +√8, - √8

Alternate,

3x^2 - 24 = 0

therefore, x^2 - 8 = 0 ..... dividing LHS and RHS by 3

x^2 - ( √8 )^2 = 0

using x^2 - y^2 = (x-y) (x+y)

therefore,

( x - √8 ) ( x + √8 ) = 0

therefore, x-√8 =0

                 x+√8=0

x=+√8       x=-√8
