If you look at either diagonal (line joining opposite angles) it forms 2 triangles that are identical, both in size and shape, but that are in different positions. So by finding the area of one using <u>base x height ÷ 2,</u> and then adding them together, you get the area of the polygon.
However, you will find that that would be the same as just doing <u>base x height</u>, so the area of a parallelogram is just that.
You use the discriminant (b²-sqr(4ac))/2a and if sqr(4ac) inferior to 0 then use i = sqr(-1)
Answer:
The solutions are -2 and 3
Step-by-step explanation:
You can find the solutions to a quadratic by looking at where the line/arch intersects the x-axis. In this case, the quadratic intersected it at -2,0 and 3,0.
The answer is 28x^2+20x.
