Question

solve 3x^2 +4X^2 I keep getting 25 but that isn't the right answer

Answer 1

is it a factoring problem?

Answer 2

\[2x^2+4x^2\] is not an equation to solve
you can add and get
\[2x^2+4x^2=6x^2\]

Answer 3

typo should be 3x^2 + 4x^2 = 7x^2

Answer 4

@nikita17 are you sure you copied all of the problem? usually to solve you are given an equation.

Answer 5

Really! I was doing 3x^2 as 3*3 =9 and 4x^2 as 4*4=16 which combined would equal 25 even the calculator agreed but it was wrong

Answer 6

This was just combining like terms these were the only 2 like terms

Answer 7

\[3x^2=3\] is not always true
you have a variable there
\[3x^2\] is three times some number \(x\) squared

Answer 8

was there a question that came along with
\[3x^2+4x^2\]?

Answer 9

yes combine like terms

Answer 10

ok now we have a question and now we can answer it
but before we do, what is three hundred plus four hundred?

Answer 11

I think triciaal was correct she said 7x^2

Answer 12

700

Answer 13

yes
and what is three hamburgers and four hamburgers?

Answer 14

or
\[3\heartsuit +4\heartsuit\]?

Answer 15

@satellite73 was correct he just had the wrong number he used 2 instead of 3

Answer 16

yes i see what you are getting at satellite 73

Answer 17

Yes I see now

Answer 18

so it is clear right?
\[3x^2+4x^2=7x^2\] on account of \(3+4=7\)

Answer 19

It was confusing because when I put the equation in my calculator it was 25 and I could also see how it came up with that

Answer 20

my dear this is not a calculator exercise
it has nothing to do with your calculator

Answer 21

Yes thank you both satellite73 and triciaal

Answer 22

remember the calculator only does what you tell it to do

Answer 23

as a matter of fact, i am willing to bet that you cannot "put the equation in the calculator"

Answer 24

our teacher had us download a special type of calculator

Answer 25

I believe triciaal is right. the calc will do what you tell it to do

Answer 26

Thanks again both of you =)

Answer 27

you are welcome
