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

Answer:
Area = 154 m²
Step-by-step explanation:
i pressume base = 14 m
height = 22 m
Area of a triangle = 1/2 * base * height
Area = 1/2 * 14 * 22
Area = 154 m²
