1.

X = root 2 b) x2 - root 2x - 4 = 0

Answer»

hi mate,

solution:

GIVEN: x = √2

The given equation is :

→x² + √2 x - 4 =0

By splitting the MIDDLE term,we can write the equation as

→ x² + 2 √2 x - √2 x - 4=0

→ x² + 2 √2 x - √2 x - 2√2×√2 =0

→ x ( x + 2 √2 ) - √2 (x + 2√2) = 0

→ (x - √2) (x + 2 √2) = 0

→ x - √2 =0 and x + 2√2=0

→ x= √2 and x = - 2 √2 , are solution of the equation.

i hope it helps you.
