1.	Find the roots of the 3√ 2 x2 - 5x -√ 2 = 0 quadratic equations by the factorisation method.
Answer» ANSWER: =3√2x^2-5x-√2 =3√2x^2-6x+x-√2 =3√2x(x-√2) +1(x-√2) =(3√2x+1) (x-√2) =0 =3√2x+1=0 =3√2x=-1 =x=-1/3√2 it is not POSSIBLE =(x-√2) =0 =x=√2 it is possible hence, x=√2 is RIGHT answer.

Find the roots of the 3√ 2 x2 - 5x -√ 2 = 0 quadratic equations by the factorisation method.

Answer»

ANSWER:

=3√2x^2-5x-√2

=3√2x^2-6x+x-√2

=3√2x(x-√2) +1(x-√2)

=(3√2x+1) (x-√2) =0

=3√2x+1=0

=3√2x=-1

=x=-1/3√2 it is not POSSIBLE

=(x-√2) =0

=x=√2 it is possible

hence,

x=√2 is RIGHT answer.
