Use completing the square to solve the equation x2+16x=−44 . first determine the number you must add to both sides of the equation. what is the correct answer? 64; −8±25⎯⎯√ 44; −8±45⎯⎯√ 256; −8±25⎯⎯√ 64; 8±20⎯⎯⎯⎯√

We will add 64 to both sides.

x=8±√20

Step-by-step explanation:

Here we are given the equation:

Now we take half of the coefficient of x and add it to x.

Coefficient of x is 16, half of 16 is 8.

Also we add square of 8 to both sides.

So new equation becomes:

Completing the square:

NOw let us  simplify it to get the value of x.

Taking square root on both sides:

Bringing 8 to the right side:

x=8±√20

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
