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

Answer:

Take the square root of both sides of the equation.

Step-by-step explanation:

The given quadratic equation is :

$x^{2} =\frac{9}{16}$

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

That can be depicted as :

$\sqrt{x^{2} } =\sqrt{\frac{9}{16} }$

Now we can solve this as :

$\sqrt{x \times x} =\sqrt{\frac{3\times3}{4\times4} }$

That gives, $x=\frac{3}{4}$
