For example, solving for b in the equation below prints the following "show your work" steps taken to solve the equation.
1−> a=b+1/b
1
#1: a = b + –
b
1−> b
level 1: a = b + (1/b)
Subtracting "b" from both sides of the equation:
level 1: a - b = 1/b
Subtracting "1/b" from both sides of the equation:
level 1: a - b - (1/b) = 0
Subtracting "a" from both sides of the equation:
level 1: -1*(b + (1/b)) = -1*a
Dividing both sides of the equation by "-1":
level 1: b + (1/b) = a
Unfactoring...
level 1: b + (1/b) = a
Solving for zero...
level 1: b + (1/b) = a
Subtracting "b" from both sides of the equation:
level 1: 1/b = a - b
Multiplying both sides of the equation by "b":
level 1: 1 = (a - b)*b
Subtracting "1" from both sides of the equation:
level 1: 0 = ((a - b)*b) - 1
Solve for zero completed:
level 1: 0 = ((a - b)*b) - 1
Checking if equation is a polynomial equation:
level 1: 0 = (a*b) - b^2 - 1
Equation is a degree 2 polynomial equation in (b).
level 1: b = 0.5*(a - (((a^2 - 4)^0.5)*sign))
Equation was solved with the quadratic formula.
Solve completed:
level 1: b = 0.5*(a - (((a^2 - 4)^0.5)*sign))
1
(a − (((a^2 − 4)^–)*sign))
