Jennifer is completing the square to solve the quadratic equation

2 - 1 - 3 = 0.

What should be her first step?

Isolating the constant, - 3

adding - 3 to both sides of the equation

Isolating the first term, z2

adding - x to both sides of the equation

The first step in completing the square is Isolating the constant - 3.

Step-by-step explanation:

To solve the quadratic equation of the form ax^2+bx+c = 0

step 1: Isolate the constant term and keep the x terms together. where 'c' is the constant and 'a', 'b' are coefficients of x terms.

Here, the constant term c = - 3. So, the right answer is Isolating the constant, - 3

step 2: Convert the x terms in the form of algebraic expression

(a+b) ^2 = a^2+2ab+b^2 to make a complete square.
