Question

Maya is solving the quadratic equation by completing the square.4x2 + 16x + 3 = 0What should Maya do first?Isolate the variable x2.Subtract 16x from both sides of the equation.Isolate the constant.Factor 4 out of the variable terms.

Answer 1

Isolate the constant
4x^2+16x=-3

Answer 2

Isolate the constant

Explanation:

Since, when we solve a quadratic equation,

We follow the following steps,

Step 1 : Move the constant term or isolate the constant term to the right side of the equation,

Step 2 : Make 1 as the coefficient of
`x^2`

Step 3 : Add the square of the half of the coefficient of x both sides of the equation.

Here the given quadratic equation is,

`4x^2+16x+3=0`

First step must be
`4x^2+16x=-3`

That is, isolate the constant term,

Third option is correct.
