The problem is in the picture :)

frozen [14]

Answer:

Last option: 4

Step-by-step explanation:

The quadratic equation simplified: $x^2-4x=-\frac{7}{2}$ has the form:

$ax^2+bx=c$

In this case, you can identify that "a", "b" and "c" are:

$a=1\\b=-4\\c=-\frac{7}{2}$

To solve this quadratic equation by completing the square, Carlos should add $(\frac{b}{2})^2$ to both sides of the equation. This is:

$(\frac{-4}{2})^2=(-2)^2=4$

Then:

$x^2-4x+4=-\frac{7}{2}+4$

Therefore you can observe that the number he should add to both sides of the equation is: 4

Assignment: $\bold{Factor \ 4u^2-28u+49}$

<><><><><>

Answer: $\boxed{\bold{\left(2u-7\right)^2}}$

<><><><><>

Explanation: $\downarrow\downarrow\downarrow$

<><><><><>

[ Step One ] Rewrite $\bold{4u^2-28u+49}$

$\bold{\left(2u\right)^2-2\cdot \:2u\cdot \:7+7^2}$

[ Step Two ] Apply perfect square formula

Note: Perfect Square Formula: $\bold{\left(a-b\right)^2=a^2-2ab+b^2}$

$\bold{a=2u,\:b=7}$

$\bold{\left(2u-7\right)^2}$
