I'll assume that's - 5c. Then you're looking for numbers that multiply to -24 and add to -5. That's -8 and 3.
(c - 8)(c + 3) = 0
c = 8, -3
Solve this problem -x squared -40x- 80 =0
X=1
If x squared -10 = 0 then x = the square root of 10
You have to put your heart into it!

x = 25 / 3squared + 5
Without an "equals" word or sign somewhere, there is nothing to solve.You only have an expression, not an equation.
It can be solved by using the quadratic equation formula.
Your Problem: X - 4 = ?Current Problem: 3 [squared] - 4 = ?How: When a numbered is squared, it means you multiply it against itself. So, 3 squared equals 3x3.3x3 = 9So, you would then take 9 and minus it by 4, which would than equal 5.Answer:3 [squared] - 4 = 5or9 - 4 = 5
Yes and x = 2+square root of 6 or x = 2-square root of 6
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
