-According to the figure, Δ is congruent to Δ
.
So, if the length of is 30, then the length of
is also 30, because
.
Start with
Multiply both sides by 5:
First in factoring, you must find out what is common in the whole equation
Now, make 2 sets of parentheses and "split up" the rest of the equation
Try to experiment which numbers work out
We are not subtracting anything so both parentheses are positive
Therefore, the factored version of
