Question

9+-3√33
---------
-18

Answer 1

quadratic equations

Answer 2

why can't you just add 3 to 9? why do you have to divide?

Answer 3

is it because 3 is being multiplied by the square root of 33 or is it because 3 has a radical sign by it?

Answer 4

btw this was the process of solving the quadratic equation. the original problem was

Answer 5

-10x^2-9x+1

Answer 6

You can't add the 3 because it's being multiplied by the square root of 33.

Answer 7

so only because it's being multiplied?

Answer 8

Wait is the equation meant to be 9 plus or minus the square root of 33?

Answer 9

yes

Answer 10

9 +- 3 square root of 33

Answer 11

Oh yeah, my bad. When you have two things being multiplied and something added, you have to go by the order of operations. Multiplication comes before adding. So you multiply \[3 * \sqrt{33} = 17.2336\]
Then you add 9 and subtract 9. Two different equations
\[17.2336 - 9 = 8.2336\]
\[17.2336 + 9 = 26.2336\]
Divide both by -18. The answers should be -.457 and -1.457

Answer 12

uhmm... without it being put into a decimal

Answer 13

by just leaving the radicals under a square sign

Answer 14

without finding their square root

Answer 15

im guessing it's because it's 3 being multiplied by the square root of 33
