Question 777073: which strategy do I use to factor 18z+45+z^2 ?
Answer by 1998Baby(63) (Show Source): You can put this solution on YOUR website!
first make it into standard form
z^2+18+45
then you have to find numbers that when multiplied equal 45 and when added equal 18.
the numbers would be 15 and 3
then you put them in the equation.
z^2+15z+3z+45
then you factor by grouping
z(z+15)+3(z+15)
if you did it right you should have the same numbers in the parenthesis.
then you put z+3 together
the final answer should look like this: (z+3)(z+15)
if you had the equation like this in the beginning: 18z+45+z^2=0 the answer would be z=-3,-15
