Step-by-step explanation:
(Remember to set g(x) to zero).
For this, I will be completing the square. Firstly, what two terms have a product of 8x^2 and a sum of 6x? That would be 4x and 2x. Replace 6x with 2x + 4x:
Next, factor -x^2 + 2x and 4x - 8 separately. Make sure that they have the same quantity on the inside of the parentheses:
Next, you can rewrite the equation as
Now apply the Zero Product Property:
<u>The zeros of this equation are 4 and 2.</u>
Answer = Red portion
Firstly, find out the area of the red portion (the area around the centre).
The three figures around the centre are trapeziums, so use the trapezium area equation.
a + b / 2 x h
4.5 + 5 = 9.5
9.5 / 2 = 4.75
4.75 x 1.5 = 7.125
As there are three trapeziums, times the area by 3.
7.125 x 3 = 21.375
Area of red portion = 21.375

Next, find out the area of the blue portion.
As the blue portion is in the centre and the figure at the centre is an equilateral triangle, use the equilateral triangle area equation.
root 3 / 4 x a^2
root 3 / 4 x 5^2 = 10.83 (rounded to 2 d.p)
—
Area of red portion = 21.375
Area of blue portion = 10.83
This means that the red portion has a greater area.
Hope this helps :)
