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

Let a =107° and b=42°;
So cos 107° cos 42° + sin 107° sin 42° = cosa.cos42 + sina.sinb = cos(a-b)
and cos 107° cos 42° + sin 107° sin 42° = cos(107-42) = cos(65°)
The answer to this question would be true.
In this case, you are given a sentence containing a condition to fulfill. To answer this question, you need to understand the sentence and turn it into an equation then compare it with the condition. The equation for this question would be: 170 * 1/10= 17.
The answer is true because the result of 170 * 1/10 is 17
