What is the hardest equation to solve?
In 2019, mathematicians finally solved a math puzzle that had stumped them for decades. It’s called a Diophantine Equation, and it’s sometimes known as the “summing of three cubes”: Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100.
How do you make 21?
We know that 1 multiplies with 21 to make 21, so they are both factors. 2 is not a factor of 21, because we cannot multiply it with another whole number to make 21.3 is a factor of 21, because it multiplies with 7 to make 21. Therefore the factors of 21 are 1, 3, 7 and 21.
How do you know if a solution is complex?
The expression b2 − 4ac is called the discriminant, and can be used to determine whether the solutions are real, repeated, or complex: 1) If the discriminant is less than zero, the equation has two complex solution(s). 2) If the discriminant is equal to zero, the equation has one repeated real solution(s).
What is the factor of 21?
The factors of 21 are 1, 3, 7, 21 and its negative factors are -1, -3, -7, -21.
What gives me 21?
1 x 21 = 21. 3 x 7 = 21. 7 x 3 = 21. 21 x 1 = 21.

What is the most complicated equation in the universe?
So what’s the most (but not needlessly) complicated equation in the universe? Arguably, it’s the Standard Model Lagrangian, which covers the dynamics of every kind of particle and all of their interactions. Notably, it doesn’t cover gravity, but be cool. It’s a work in progress.
