First turn then into a decimal, it will be easier to divide. Then, divide the decimal. Take your answer and turn it into a fraction. If it's improper, turn it into a mixed number and simply it, if you have any questions ask
6% means 6/100 or 0.06
"of" means "times"
0.06 x 300 = 18
-2(5)^2+2(5)-3
-2(25)+10-3
-50+10-3
-40-3
=-43
For the given trinomial

We need to multiply a by c

We split the middle term with these two factors

To obtain,

We now factor

This implies
