The first three steps of completing the square to solve the quadratic equation x2 +4x-6=0

Mathematics

Answer:


Step-by-step explanation:

1.  Move the 6 to the other side:   x^2 +4x                        =6

2.  Square half the coefficient of the x term:  (4/2)^2 = 4

3.  Add this 4, and then subtract this 4, from x^2 + 4x:

     x^2 +4x + 4 - 4                       =6

4.  Rewrite this perfect square as the square of a binomial:

      (x + 2)^2   -   4   = 6

5.  Add 4 to both sides:    (x + 2)^2 =  10

6.  Find the sqrt of both sides:  x + 2 = √

What is simplest form?
Vanyuwa [196]
Simplest form if I had to explain it would be the lowest number you can get to when using fractions. example, 5/10 in simplest form would be 1/2 because 5 divided but 5 is 1 and 10 divided by 5 is 2 so the answer is 1/2
