Answer:
tue
Step-by-step explanation:
You need a common denominator while subtracting because really a fraction is a division problem and you cannot do 4/5-8/9 it does not make sense as for multiplication you really just multiplying everything that is why it makes sense.
x^2−17x+30=0
Step 1: Factor left side of equation.
(x−2)(x−15)=0
Step 2: Set factors equal to 0.
x−2=0 or x−15=0
x=2 or x=15
The answer would be 16.
you have to multiply 4 and 8 which =32 and then divide 32 by 2 which =16
