Question

solve the t^3-12t+3=0

Answer 1

Reorder the terms: -12T + 3T3 = 0 Solving -12T + 3T3 = 0 Solving for variable 'T'. Factor out the Greatest Common Factor (GCF), '3T'. 3T(-4 + T2) = 0 Factor a difference between two squares. 3T((2 + T)(-2 + T)) = 0

Answer 2

It's t^2-12t+3=0
Then we can use quadratic formula
-b+-root over b^2-4ac/2a
12+- root 144-4*3/2
12+- root 132/2
12+- root 66*2/2
Take 2 common
2(6+- root 33)/2
Therefore roots of this eq are 6+root33,6-root 33
