Recall that the sum of all interior angles in a triangle is 180°, therefore F + U + N = 180°, and thus
2r2+2r−24=0
Step 1: Factor left side of equation.
2(r−3)(r+4)=0
Step 2: Set factors equal to 0.
r−3=0 or r+4=0
r = 3 or r = −4
You need to annex the zeroes. Don't worry about the 9 zeroes. Just do 5*1 which equals to 5. Then add the 9 zeroes back.
5,000*1,000,000 = 5,000,000,000
