Rewrite the equation by completing the square. x^2-x-20=0
(x+ ? )^2= ?

please help me

Step-by-step explanation:

Hi there!

This equation is written in the form . First, use partial factoring:

For x^2-x, the b value is -1 in . To complete the square, take the square of half of 1 and add it in the parentheses as the c value:

However, when adding values to one side of the equation, we must to the same to the other side:

Complete the square:

Move 20 to the other side

I hope this helps!

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
