The required steps are
2x^2 + 12x – 3 = 0.
2x2 + 12x = 3
2(x^2+6x) = 3
2[(x+3)^2 - 9] = 3
Completing the square method
Quadratic equations are equations that has a leading degree of 2
Given the equation below;
2x^2 + 12x – 3 = 0.
Add 3 to both sides
2x2 + 12x = 3
Factor out 2
2(x^2+6x) = 3
Complete the square
2(x^2+6x+3^2-3^2) = 3
2[(x+3)^2 - 9] = 3
This gives the required steps to solve the equation
