Step-by-step explanation:






Answer:
cool, how long did it take
Answer:
This means c=100. The factored form is
.
Step-by-step explanation:
A perfect square is a trinomial that factors into the form
. To find the value of C to finish the perfect square divide 20 by 2 and square it.
20/2 = 10
10*10=100
This means c=100. The factored form is
.
Answer: 107
Steps: add 12 + 106
= 118
subtract 332 - 118
= 214
divide 214/2
