The first three steps of completing the square to solve the quadratic equation x^2 + 4x - 6 = 0, are shown below. step 1: x^2 + 4x = 6 step 2: x^2 + 4x + 4 = 6 + 4 step 3: (x + 2)^2 = 10 what are they in order?

Step-by-step explanation

step 4- square root sign (x+2)^2=+- square root sign 10

step 5-  (x+2)=+-square root sign 10

step6-   x=-2+- square root sign 10

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

-1/2 +2
