expand (x-4)(3+sqrt(x+5))

expand

(x - 4) (3 + x + 5)

3 x + x x + 5 - 12 - 4 x + 5

Solution steps

(x - 4) (3 + x + 5)

Apply FOIL method

(x - 4) (3 + x + 5) : 3 x + x x + 5 - 12 - 4 x + 5

= 3 x + x x + 5 - 12 - 4 x + 5

(x - \frac{1}{2}) (x + 4) (x + 3)

(2 sin (θ) - 1) (sin (θ) + 1)

\frac{( 1 + ab ) ^{2}}{( 1 - a ^{2} ) ( 1 - b ^{2} )}

cos (2 \cdot t) U (t - π)

(tan (θ) + cot (θ)) sin (θ)
