What two numbers multiplied equals -72 but when added together equals -17?
The numbers are: 3.51041215 and -20.51041215 A more accurate answer can be found by using the quadratic equation formula
What two numbers multiplies together to get -60 and added together to be 7?
-53
If you were to factor the equation x squared minus 8 x plus 12 what must be true about the two brackets of factors?
Both of the constants must be negative. x2-8x+12 = (x-2)(x-6) That 2 numbers added together equals -8 and when multiplied equals 12 By the way it is not an equation because it is a quadratic expression.
What is it when prime numbers are multiplied together to get the original number?
Then, we obtain the multiple or the product of prime numbers.

Why are there usually two solutions to a quadratic equation?
In the graph of a quadratic equation, the plotted points form a parabola. This parabola usually intersects the X axis at two different points. Those two points are also the two solutions for the quadratic equation. Alternatively: Quadratic equations are formed by multiplying two linear equations together. Each of the linear equations has one solution - multiplying two together means that the solution for either is also a solution for the quadratic equation - hence you get two possible solutions for the quadratic unless both linear equations have exactly the same solution. Example: Two linear equations : x - a = 0 x - b = 0 Multiplied together: (x - a) ( x - b ) = 0 Either a or b is a solution to this quadratic equation. Hence most often you have two solutions but never more than two and always at least one solution.

How do you add quadratic equations?
You add compatible terms together. For example, if one equation has 3x2, and the other has 5x2, you combine those two terms as 8x2.
How do you find the vertex of the parabola given by y equals -3x2 plus 12x-1?
-3x2+12x-1 = y Solve the quadratic equation when y = 0 by means of the quadratic equation formula which gives x values of 3.914854216 and 0.085145784. Add these values together and divide them by 2 which is 4/2 = 2 and this is the line symmetry of the parabola. Substitute 2 for x into the original equation to find the value of y: So the vertex is at (2, 11) Remember that the parabola has a maximum value because the coefficient of x2 is negative in other words it will face downwards.
