The problem is a quadratic.
Rewritten as x2-x+5=0
Since this cannot be factored, the quadratic formula can be used.
I can tell there will be imaginary numbers because the discriminant is < 0
b2-4ac = 1-4(1)(5) = -19
(1±(√12-4(1)(5)))/2(1) = confusing = 1/2 ± i√19
x = 25 / 3squared + 5

X2 - 4X - 5 = 0 easy factor, what two factors of - 5 add up to - 4 (X + 1)(X - 5) X = - 1 ------------- X = 5 --------------
5 or 12
(x-5)(x+3)
x = 25 / 3squared + 5
You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve

It is: 9-4 = 5
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
5.

(x-5)(x+3)
Yes and its solutons are: x = -1 -sq rt of 6 and x -1 +sq rt of 6
The centre is (-5, 3)
minus 5
