Which function has only one x-intercept at (−6, 0)?

atroni [7]

Answer:

The only function that has only one zero at -6 is f(x) = (x + 6)(x + 6)

Step-by-step explanation:

We have a function:

f(x)=(x+6)(x+6)

This function is also equal to f(x)=(x+6)^2

This is the square of the binomial. It has only one zero

f(x)=(x+6)^2 = 0

If we take square root we get:

√(x+6)^2 = 0

x+6 =0

x= -6

The only function that has only one zero at -6 is f(x) = (x + 6)(x + 6)....

What value completes the square for the expression

oee [108]

Correct Answer: Option D. 36

The given expression is:

$x^{2} +12x$

The formula for a whole square is:

$(a+b)^{2} = a^{2} +2ab+ b^{2}$

Re-writing the given expression we get:

$x^{2} +2(x)(6)$

Comparing this expression with the formula of whole square, we can note that we have the square of first term which x, twice the product of first and second term which are x and 6. What is missing is the square of second term. The second term is 6, and square of 6 is 36. This means addition of 36 to the given expression will make it a complete square.

So, complete square will be:

$x^{2} +2(x)(6)+ 6^{2} =(x+6)^{2}$

So, correct answer is Option d. 36
