Question:
1) If c=-3, then 4c2+5c-2=
2) If x is a positive nnumber, then √36x6=
In the second one is not 36 mult. to 6, it's letter "x" in 6th power.
Kate, release Alt and type 251 on the keypad (not on the top).

I'll put ^ equals to square to simplify everything =)
y^ - 24y + 144 = 0
I used the "broom method", so i hope it won't complicate things.
(y - 12) | -12y
(y - 12) | -12y
> y^ + 144 | -24y
Therefore, y = 12
(t+7)^
= (t+7)(t+7)
[multiply t from the first bracket with (t+7) and 7 from the first bracket with (t+7)]
= t(t+7) + 7(t+7)
= t^ + 7t + 7t + 49
= t^ + 14t + 49
Do the same with (c-2d)^
(c-2d)^
= c(c-2d) + [(-2d)(c-2d)^]
= c^ - 2cd - 2cd + 4d^
= c^ - 4cd + 4d^
Sorry if it's messy =)
