Question

x²-2root2-30 please factorize it ​

Answer 1

Answer:

x = 5√2 or x = -3√2

Step-by-step explanation:

Given equation is x^2 - 2√2x - 30 = 0

=> x^2 - 5√2x + 3√2x - 30 = 0

=> x( x - 5√2 ) + 3√2( x - 5√2 ) = 0

=> ( x - 5√2 )( x + 3√2 ) = 0

=> Here x - 5√2 = 0 (or) x + 3√2 = 0

=> x = 5√2 or x = -3√2

Therefore, x = 5√2 or x = -3√2
