Question

How do I symbolize 3*(x+2)^2 + 5 to show

3x^2 + 12x + 27

Answer 1

\(\Large \color{MidnightBlue}{\Rightarrow (a + b)^2 = a^2 + 2ab + b^2 }\)

Hint..

Answer 2

Also, remember PEMDAS.

Answer 3

3(2x^2 + 4x + 4 + 5)...?

Answer 4

\(\Large \color{MidnightBlue}{\Rightarrow 3(x + 2)(x + 2) + 5 }\)

Answer 5

I want to know how to symbolize it correcly.

Answer 6

What do you mean by symbolise?

Answer 7

ParthKohli the 3 in the equation you put only multiplies the (x+2)^2

Answer 8

\(\Large \color{MidnightBlue}{ \brack3[(x + 2)(x + 2)] + 3}\)

Answer 9

I did completing the square but I want to know how I should symbolize the factorization process.

Answer 10

I will post my thoughts okay then you can tell me if I did it right

Answer 11

\(\Large \color{MidnightBlue}{\Rightarrow 3(x^2 + 4x + 4) + 3 }\)

Answer 12

\(\Large \color{MidnightBlue}{\Rightarrow 3x^2 + 12x + 12 + 5 }\)

\(\Large \color{MidnightBlue}{\Rightarrow 3x^2 + 12x + 17 }\)

Answer 13

The question is, complete the square of \[3x ^{2} + 12x + 9\]

Answer 14

Okay, that's easy.

Answer 15

Go ahead, I'll correct if any mistake

Answer 16

I know but I want to know how to symbolize it in vertex mode

Answer 17

My book says do this this 3(x^2 + 4x + 9) )
3(x^2 + 4x + )+ 9)
3(x^2 + 4x + 4)+9 - 4)
3(x+3)^2 + 5

Answer 18

My book says to put the 9 outside of a bracket that you make @ParthKohli

Answer 19

But I think it's better to keep inside so it's mathematically correct

Answer 20

3x^2 + 12x + 27
/3 /3 /3

3(x^2 + 4x + 9),

3(x^2 + 4x +4 +9 - 4)

(x^2 + 4x + 4) = (x+2)^2

3((x + 2)^2 +5)

Answer 21

Holy crap I figured it out myself!!!!!!!!!!!!!
