Also, since 12 is negative, that means one of the multiples must be negative. Therefore, -3 and 4 are the correct numbers. Since we know what the two multiples are, these equations will be: Take the 6n and bring it over to the other side of the equation, so that everything is equal to zero. Once again, the first thing you do is figure out the multiples of 5. In this case, we only have two to work with, given that 5 is prime: The new total must then add up to the middle number, However, if you make both 1 and 5, negative, it can work.
This explanation can also apply to questions 4, 6, and 7. This one is a bit trickier, and you have to know your square roots to get it right.
Since the square root of 25 is 5, and the square root of 4 is two, the equation comes out as such: Consider the general form: Related Questions Math help.

Quadratic Equations Explained A quadratic equation is an equation that looks like this: ax 2 +bx+c = 0, where a, b, and c are numbers, called coefficients. Example: x 2 +3x+4 = 0. You can think about a quadratic equation in terms of a graph of a quadratic function, which is called a parabola. The equation means that you have to find the points on the horizontal axis (x) where the graph intersects with the axis.
