Question

what is the first step in solving the quadratic equation x2 = 9/16? take the square root of both sides of the equation. add 9/16 to both sides of the equation. square both sides of the equation. subtract 9/16 from both sides of the equation.

Answer 1

Since

x² = (9/16)

The first step is to take square root of both sides.

√x² = √(9/16)

x = 3/4

Answer: take the square root of both sides of the equation

Answer 2

Take the square root of both sides of the equation.

Explanation:

The given quadratic equation is :

`x^(2) =(9)/(16)`

So, the first step will be - to take the square root of both sides of the equation.

That can be depicted as :

`\sqrt{x^(2) } =\sqrt{(9)/(16) }`

Now we can solve this as :

`√(x * x) =\sqrt{(3*3)/(4*4) }`

That gives,
`x=(3)/(4)`
