Solve x2 - 8x - 9 = 0.
rewrite the equation so that it is of the form
x2 + bx = c.

X^2 -8x = 9 is the rewritten version
I used completing the square to solve it and the work it attached below

The answer is budget i believe. hope this but it’s self explanatory.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
