Question

How would I solve 75+3x^2?

Answer 1

perhaps you mean 75+3x^2 = 0?

Answer 2

to solve u need some equality....

Answer 3

yes thats what I mean

Answer 4

Ok, rearrange to get x on its own:
3x^2 = -75
x^2 = -25
x = √-25 which is not a real number

Answer 5

Did you mean 75x+3x^2 = 0?

Answer 6

let's just mean everything shall we

Answer 7

i think it's just asking to factor out 75 + 3x^2

Answer 8

Start with the given expression Factor out the GCF 3 Now let's focus on the inner expression




------------------------------------------------------------



Looking at we can see that the first term is and the last term is where the coefficients are 1 and 25 respectively.

Now multiply the first coefficient 1 and the last coefficient 25 to get 25. Now what two numbers multiply to 25 and add to the middle coefficient 10? Let's list all of the factors of 25:



Factors of 25:
1,5

-1,-5 ...List the negative factors as well. This will allow us to find all possible combinations

These factors pair up and multiply to 25
1*25
5*5
(-1)*(-25)
(-5)*(-5)

note: remember two negative numbers multiplied together make a positive number


Now which of these pairs add to 10? Lets make a table of all of the pairs of factors we multiplied and see which two numbers add to 10

lol looks the same answer as the one here http://www.algebra.com/algebra/homework/Polynomials-and-rational-expressions/Polynomials-and-rational-expressions.faq.question.142171.html

i think @jim_thompson5910 wrote it =)))

Answer 10

and fyi @justindrake that problem is so different from this one =))))

Answer 11

What a coincidence! Wow! Jim_Thompson!

Answer 12

@lgbasallote My Answer Is Right

Answer 13

the problem reads 75+3x^2=0.
so i move the 3x^2 to the other side is that what you said?

Answer 14

*your* answer?
