X = Heather's age NOW
x - 2 = her age 2 years ago
x - 3 = her age 3 years ago
The Least Common Multiple of 2 and 3 is 6. Multiply both sides by 6.
The required steps are
<em>2x^2 + 12x – 3 = 0. </em>
<em>2x2 + 12x = 3</em>
<em>2(x^2+6x) = 3</em>
<em>2[(x+3)^2 - 9] = 3</em>
<h3>Completing the square method</h3>
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
