Answer: I’ll give you an example of how to do it by solving number 9 - h^2 + 8h + 16
Step-by-step explanation:
Step 1: Find two numbers that when you multiply them it gives you the first term’s coefficient multiplied by the last term’s coefficient (1x16 = 16) and when you add them it gives you the second term’s coefficient (8). The numbers in this case are positive 4 and positive 4.
Step 2: Create two parenthesis with the letter accompanied by the numbers. (h + 4)•(h+4). And that’s how you factor.
In case the first term is elevated to the third you will have to take out GCF (greatest common factor) first. If the numbers are too high like in the exercise number 15 you can also take out GCF and it will make it a lot easier to solve. Sometimes what you write on the parenthesis in the step 2 can be simplified, if that’s so then you would have to do it in order to get the correct answer.
Hope this helps you.
Find the slopes of the sides of the triangles:
Slope of AB = 9
Slope of BC = 1
Slope of CA = -1
The triangle is a right triangle as BC and CA are perpendicular* to each other, which means that angle ACB = 90.
* If a slope is the negative reciprocal of another slope, they are perpendicular
Construct a lunge segment from Side AB to side AC but make sure it is at a 90 degree angle or at least make it as close as possible.
