To make x^2 + 2x a perfect square we need to add the term { 2 / (2*1) }^2
which equals 1.
Add 1 to both sides: x^2 + 2x = 8
add 1 to both sides: x^2 + 2x + 1 = 8 + 1 (x + 1)^2 = 9
Take square root on both sides: x + 1 = +/- 3 x = +3 - 1 or x = -3 - 1 x = 2 or x = -4
Answer:
Step-by-step explanation:
-10 (d+1) = -14
-10d -10 = -14
-10d = -14 + 10
-10d = -4
d = 4/10
d= 2/5
Answer:9
Step-by-step explanation:because when we add 7+7+6+6=26 then we will going to 35-26= 9 im not sure so don’t hate me if it was wrong
Answer:
4
Step-by-step explanation:
One way to do it: The y-axis is the vertical axis. The point is at 4 on the y-axis.
Another way to do: Coordinates of the point = (2,4)
The y-coordinate is the second number.
The answer is (x-2)^2(x-1)^2-4x+2
