The complete equation is x^2 + 13x + 169/4 = 157/4
<h3>How to determine the number that completes the square?</h3>
The equation is given as:
x^2 + 13x = -3
Let the coefficient of x be represented with k.
So, we have:
k = 13
Divide both sides
k/2 = 13/2
Square both sides
(k/2)^2 = 169/4
Add 169/4 to both sides of the equation
x^2 + 13x + 169/4 = -3 + 169/4
Evaluate the sum
x^2 + 13x + 169/4 = 157/4
Hence, the complete equation is x^2 + 13x + 169/4 = 157/4

Answer: x = 3
Step-by-step explanation:
First you need to start by adding positive 4x to both sides since the 4x is a negative. 4x + (-7x) = -3x. Then it is just simply -3x+2 = -7. Since 2 is a positive number subtract both both sides by 2. Then you should get -3x = -9. Then divide both sides by -3 and the answer is x = 3.
