Question

Which of the following is a solution of x2 - 10x = -36?

Answer 1

add 36 to both sides, and factor.

Answer 2

Set it equal to 0 (as a quadratic), factor, and see what your zeros/solutions are.

Answer 3

so it would be x2-10x=36+0?

Answer 4

\[x ^{2}-10x = -36\rightarrow x ^{2}-10x+36=0\]

Answer 5

Factor:
\[x ^{2}-10x+36\]

Answer 6

6 and 4

Answer 7

but those arent the answer choices

Answer 8

they have to deal with i's

Answer 9

Which of the following is a solution of x2 - 10x = -36?

negative 5 minus i sqare root of 61

5 plus i square root of 61

negative 5 minus i square root of 11

5 plus i square root of 11

Answer 10

No wait

Answer 11

^ are the answer choices

Answer 12

Yes, because x^2-10x+36 has no real roots

Answer 13

exactly

Answer 14

So, we must use the quadratic formula.

Answer 15

Expect the discriminant to be (-)

Answer 16

oh what joy im horrible at the quadratic formula

Answer 17

Well in the form x^2-10x+36

We know a, b, and c
