## Story Problem Solving by Finding Zeros

To start i factored out 16 and got the problem to be -t^2+6t+7 then I put it into the T chart and tried to find multiplied to be -7 and added up to be a +6. Those number were (7 and -1) I plugged those numbers into my equation and the new equation was (-t^2+7t)(-1t+7) then I factored out a t from the first parentheses and a positive 1 from the second parentheses and got the final answer to be (t+1)(-t+7) then set them both equal to zero and the answers were t=-1 and t=-7

## Solving Complex Numbers

## Addition combine like terms, add, and solve | ## Subtraction combine like terms, subtract, and solve | ## Foil multiply the first number times the numbers in the parentheses then multiply the second number times the parentheses, combine like terms, and solve |

## Dividing multiply the top and bottom X -3i substitute the i^2 for a -1, plug in, solve, and reduce | ## Multiplication multiply the top and bottom X 2-3i substitute the i^2 for a -1, plug in, and solve |

## Vertex Form The vertex was (1,3) so i plotted that point onto my graph then the -2 in front of the parentheses showed me that the other points were going to be down 2 and over one | ## Standard Form plug into T chart, find the points for X and Y, and solve by plugging it in a graph |
