Question

6. [9.02] What are the solutions of x^2 − 3x − 28 = 0? (4 points)
x = 4, x = 7
x = −4, x = −7
x = 4, x = −7
x = −4, x = 7

Answer 1

did you factor
\[x^2-3x-28\]?

Answer 2

no

Answer 3

that is what you need to do first

Answer 4

okay.

Answer 5

it is pretty clear form your answer choices that it is either
\[(x-4)(x+7)\] or \[(x+4)(x-7)\] see which one works

Answer 6

(x-7)(x+4)=0
x=7,-4

Answer 7

yup

Answer 8

thanks!

Answer 9

yw, you did all the work
