Question

Substitute x = (- 1 + 2√2)/4 in the equation (4x + 1)² - 8 = 0 and check whether the value satisfies the given equation.

Answer 1

The value of  x = (- 1 + 2√2)/4 satisfies the given equation.

What is an Equation ?

An equation is a mathematical statement formed when two algebraic expressions are equated by an equal sign.

The equation given is

(4x + 1)² - 8 = 0

x =  (- 1 + 2√2)/4

To check whether it satisfies the equation

( 4 * ( (- 1 + 2√2)/4) +1)² -8 = 0

(-1 + 2√2  +1)² - 8 = 0

(2√2)² -8 = 0

8-8 = 0

As LHS = RHS ,

hence the value of  x = (- 1 + 2√2)/4 satisfies the given equation.
