Question

(z - 5) x (z - 2)

Answer 1

Is that (z - 5)(z - 2)?

Answer 2

yes @Unanimoose

Answer 3

If so we can distribute z into z and -2, and then 5 into z and -2.

z * z = ?
z * -2 = ?
-5 * z = ?
-5 * -2 = ?

Solve all these and then combine like terms

Answer 4

z*z=z^2
i dont know the second one
-5*z= -5z
-5*-2=10

Answer 5

@Unanimoose

Answer 6

z * -2 is the same as -2 * z. :)

Answer 7

so whats the answer?

Answer 8

So it would be like -5 * z but with -2.

Answer 9

answer?

Answer 10

So we have: z^2 - 2z - 5z + 10

Do you know which terms are like terms?

Answer 11

2z & 5z

Answer 12

Yeah, but they are negative. What do we get when we combine them?

Answer 13

-7

Answer 14

-7z

Answer 15

Yep, so just put that in as the second term and you have your final form.
