expand (14tan(θ)-5)(17tan(θ)+16)

expand

(14 tan (θ) - 5) (17 tan (θ) + 16)

238 tan^{2} (θ) + 139 tan (θ) - 80

Solution steps

(14 tan (θ) - 5) (17 tan (θ) + 16)

Apply FOIL method

(14 tan (θ) - 5) (17 tan (θ) + 16) : 238 tan^{2} (θ) + 139 tan (θ) - 80

= 238 tan^{2} (θ) + 139 tan (θ) - 80

(4 x - π)^{2}

y sec (x) d x - (y + 1) tan (x) d y

(72 + x) (72 - x)

\frac{( - 1 + 2 α - α ^{2} ) ( ψ e ^{(1 - α) ψ u} )}{( 1 - u ) ^{α}}

(e^{\frac{x}{150}} - e^{- \frac{x}{150}})^{2}
