In order to factor the quadratic, we need to find the values of a, b and c for the given quadratic
Now, let us apply ac method to factor the quadratic.
-24 could be factored in two numbers 8 and -3 that add upto 5.
Therefore, middle term 5x of expression
Then we need to make the break the expression into groups.
Factor out 3x form
Then factor out common parenthesis
We got factored form
Factor out common parenthesis
By applying zero product rule, we need to set each factor equal to zero and solve for x.
Consider the region below
Approximate the area of the region using six rectangles. Use the midpoints of each subinterval for the heights of the rectangles. The area is approximately how many square units?
