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

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

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

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

    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

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