Solving by completing the square
x²+6x=-5
Step 1- Take B and divide it by 2 and after you divide it by 2 square it and that should equal 9.
Step 2- Add 9 to both sides of the equation.
Step 3- Factor the first part of the equation and add -5 plus 9.
Step 4- Square root both sides of the equation.
Step 5- Now you add x + 3 = 2 and x + 3 = -2 thus getting your solutions.
x²-10x=-9
Step 1- Take b and divide it by 2 square it and that should equal 25
Step 2- Add 25 to both sides
Step 3- Factor the first part of the equation and add -9 to 25
Step 4- Square root both sides of the equation
Step 5- Now you add x - 5 = 4 and x - 5 = -4
Step 1- Take B and divide it by 2 and after you divide it by 2 square it and that should equal 9.
Step 2- Add 9 to both sides of the equation.
Step 3- Factor the first part of the equation and add -5 plus 9.
Step 4- Square root both sides of the equation.
