Angelina is starting to save $950 to buy a new phone. In February, she saved $5. In March, she saved twice as much as she saved in February, for a total savings of $15 ($5 + $10). If Angelina continues to save twice as much each month as she saved the previous month, in which month will her total savings be enough to buy the phone? How much will she have saved? Once she purchases the phone, how much will she have left over?

Demonstrate the proof of your new polynomial identity through an algebraic proof and a numerical proof in an engaging way! make it so the whole world wants to purchase your polynomial identity and can't imagine living without it! you must: label and display your new polynomial identity prove that it is true through an algebraic proof, identifying each step demonstrate that your polynomial identity works on numerical relationships create your own using the columns below. see what happens when different binomials or trinomials are combined. square one factor from column a and add it to one factor from column b to develop your own identity. column a column b (x − y) (x2 + 2xy + y2) (x + y) (x2 − 2xy + y2) (y + x) (ax + b) (y − x) (cy + d)
