Question

Find the product of (x − 3)2.

x2 + 6x + 9

x2 − 9

x2 − 6x + 9

x2 + 9

Answer 1

Same thing?

Answer 2

x^2 - 9?

Answer 3

\(\Large \color{Midnightblue}{\rightarrow (a - b)^2 = a^2 + b^2 - 2ab }\)

Answer 4

Basically,
\(\Large \color{Midnightblue}{\rightarrow (a \pm b)^2 = a^2 + b^2 \pm 2ab }\)

Answer 5

x^2 - 9 - 2x^3?

Answer 6

x^2 + 9 - 6?

Answer 7

- 6x*

Answer 8

\(x^2 + 9 - 6x\)

Answer 9

Explain please...

Answer 10

Why - 6x?

Answer 11

\(\Large \color{Midnightblue}{\rightarrow (x - 3)^2 = x^2 + 3^2 - 2(x * 3) }\)
\(\Large \color{Midnightblue}{\rightarrow (x - 3)^2 = x^2 + 3^2 - 6x }\)

Answer 12

I see.

Answer 13

But that's not one of my options..

Answer 14

@ParthKohli That's not one of my options..

Answer 15

@ParthKohli That's not one of my options..

Just simplify it.

Answer 17

Umm... How?

Answer 18

\(\Large \color{Midnightblue}{\rightarrow x^2 + 9 -6x }\)

Answer 19

\(3^2 = 9\)

Answer 20

None of them are my options either..

Answer 21

It's the third one!

Answer 22

Try this using distributive property .
(x-3)(x-3)

x*x+(-3)(-3)+(-3)x+(-3x).
x^2+9-6x

Answer 23

My answer was right, but it wasn't according to the degrees.
