What number must be added to the expression below to complete the square? x² - 18x

kiruha [24]

Answer:

$\boxed {\boxed {\sf 81}}$

Step-by-step explanation:

The standard form of a quadratic is:

$ax^2+bx+c$

To complete the square, the a (leading coefficient) must be 1 and there can only be terms with variables on one side.

The expression given:

$x^2-18x$

follows these rules. Next, we divide the b (linear coefficient) by 2, then square it. Basically:

$(\frac{b}{2})^2$

The b in the expression is -18.

$(\frac{-18}{2})^2$

$(-9)^2= -9*-9= 81$

This is the number that is added.

I need help with this within the next /0 mins sum1 plz help

guajiro [1.7K]

Answer: Second option.

Step-by-step explanation:

Given the function f(x), which is:

$f(x)=x$

And given the function g(x), which is:

$g(x)=2$

You need to substiute the function $g(x)=2$ into the function $f(x)=x$ in order to find $(fog)(x)$ .

Therefore, through this procedure, you get this answer:

$(fog)(x)=(2)$

$(fog)(x)=2$

You can observe that this matches with the second option.
