tan(2x) = 2tanx/(1 - tan2x)
So tan(2x) +1 = 2tanx/(1 - tan2x) + 1
= 2tanx/(1 - tan2x) + (1 - tan2x)/(1 - tan2x)
= (-tan2x + 2tanx + 1)/(1 - tan2x)

What is the solution when y equals 2x plus 1 is a tangent to the circle 5y2 plus 5x2 equals 1?
If y = 2x+1 is a tangent line to the circle 5y^2 +5x^2 = 1 then the point of contact is at (-2/5, 1/5) because it has equal roots
When does 1 plus 1 equal 3 and 2 minus 1 equal 2?

How do you subtract fractions with a negative fraction?
if the question u are asking is something like this 1/2 - ( - 1/2 ) then the answer is simple all you have to do is solve the equation like this 1/2 - ( - 1/2 ) = 1/2 + 1/2 = 2/2 = 1 its the - (-1/2) that is important remember the rule minus and minus equal plus plus and plus equal plus minus and plus equal minus remember and i hope it helps :)
