What are the solutions of the equation 9x4-2x2-7=0? use u substitution to solve.

Answer : The solutions of the equation are, and

Step-by-step explanation :

As we are given that the expression of equation as:

Let , we get:

Now split this expression by middle term splitting method.

(9u+7) = 0 and (u-1) = 0

and u = 1

As,

Thus, the value of 'x' for is:

The value of 'x' for is:

Therefore, the solutions of the equation are, and
