The first few steps in solving the quadratic equation 8x2 + 80x = −5 by completing the square are shown.
8x2 + 80x = −5
8(x2 + 10x) = −5
8(x2 + 10x + 25) = −5 +
which number is missing in the last step?
−200
−25
25
200

The first few steps in solving the quadratic equation by completing the square are

1 step.

2 step. Form in brackets a perfect square.

3 step. Add 200 to both sides of equation:

200, correct choice is D

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.
