x2-10 = 4x+11
x2-4x-10-11 = 0
x2-4x-21 = 0
(x+3)(x-7) = 0
x = -3 and x = 7
Solve this problem -x squared -40x- 80 =0
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

You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
x * x - 9 = 0 PEMDAS = Multiplication first. What multiplied it self equals nine? 3. So x = 3

Solve using the quadratic formula
X=1
If x squared -10 = 0 then x = the square root of 10
You have to put your heart into it!

hello
x = 25 / 3squared + 5
Without an "equals" word or sign somewhere, there is nothing to solve.You only have an expression, not an equation.
That factors to (x + 1)(x - 3) x = -1, 3
It can be solved by using the quadratic equation formula.
