Consider the equation: x^2 = -8x – 7
1) Rewrite the equation by completing the square.
Your equation should look like (x + c)^2 = d or (x – c)^2 = d.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
