Learn how to solve definite integrals problems step by step online. Solve the trigonometric equation 2tan(x)^2-tan(x)+-10=0. We can try to factor the expression 2\tan\left(x\right)^2-\tan\left(x\right)-10 by applying the following substitution. Substituting in the polynomial, the expression results in. Factor the trinomial 2u^2-u-10 of the form ax^2+bx+c, first, make the product of 2 and -10. Now, find two numbers that multiplied give us -20 and add up to -1.
