WebDec 20, 2024 · Solution. We can solve this equation using only algebra. Isolate the expression tanx on the left side of the equals sign. 2(tanx) + 2(3) = 5 + tanx 2tanx + 6 = 5 + tanx 2tanx − tanx = 5 − 6 tanx = − 1. There are two angles on the unit circle that have a tangent value of − 1: θ = 3π 4 and θ = 7π 4. WebFirst step, make sure the equation is in the format from above, ax^2 + bx + c = 0 ax2 +bx +c = 0: x^2+4x-21=0 x2 + 4x − 21 = 0 a a is the coefficient in front of x^2 x2 , so here a = 1 a = 1 (note that a a can’t equal 0 0 -- the x^2 x2 is what makes it a quadratic). b b is the coefficient in front of the x x , so here b = 4 b = 4 . c c
Webbasically you're looking b and c, which in this case are the same, so you can plug everything into the discriminant equation (b^2 -4ac): n^2 -4 (5.5) (n)=-40 i don't know if i'm being dumb and there's an easier way to solve this but you can simplify this to: n^2 -11n +40 =0 WebMar 26, 2016 · How to Solve a Trigonometry Equation Using the Quadratic Formula.
