Answer:

$x^2+\frac{4}{5}x+\frac{4}{25} $

$\left(x+\frac{2}{5} \right)^2$

Step-by-step explanation:

Taking the middle coefficient:

ax^2+bx+c

$c=\left(\frac{b}{2} \right)^2$

$c=\left(\frac{\frac{4}{5} }{2} \right)^2$

$c=\left(\frac{4 }{10} \right)^2$

$c=\left(\frac{2 }{5} \right)^2$

$c=\frac{4}{25} $

Completing the square:

$x^2+\frac{4}{5}x+\frac{4}{25} $

$\left(x+\frac{2}{5} \right)^2$

Math is confusing :(
Marta_Voda [28]

Answer:

The evaluation of the equation 3 .912+s=5.313 yields; s = 1.401

Evaluation of one variable equation

According to the questions;

We are required to evaluate the equation; 3 .912+s=5.313

Hence, we must subtract 3.912 from both sides of the equation as follows;3 .912+s -3.912 = 5.313 - 3.912.s = 1.401
