2y2 - 2y - 24 has the factors (2y + 6) and (y - 4)
There is a formula, but I always use trial and error.
The factors of the non-x element need to be such that they can be added to give the middle element.
So when you get 24, then you need to be looking at 2,12 - 3,8 - 4,6
When both the second and third element are minus values then there is a plus and a minus in the factors.

Two numbers have a product of 80 their sum is 24?
Let's denote the two numbers as x and y. We know that xy = 80 and x + y = 24. We can solve this system of equations by substituting one equation into the other. By substituting y = 24 - x into the first equation, we get x(24 - x) = 80. Simplifying this equation gives us a quadratic equation: x^2 - 24x + 80 = 0. Solving this quadratic equation will give us the values of x and y.
How many sides does an irregular polygon have if it has 252 diagonals showing work?
Let its sides be x and rearrange the diagonal formula into a quadratic equation:- So: 0.5(x^2-3x) = 252 Then: x^2-3n-504 = 0 Solving the quadratic equation: gives x a positive value of 24 Therefore the polygon has 24 sides irrespective of it being irregular or regular
What are the solutions for the quadratic equation x2 minus 21x equals 72?
x2 - 21x = 72x2 - 21x - 72 = 0(x - 24) (x + 3) = 0x = 24x = -3
