expand (u-2)(sqrt(4u+1)+3)

expand

(u - 2) (4 u + 1 + 3)

u 4 u + 1 + 3 u - 2 4 u + 1 - 6

Solution steps

(u - 2) (4 u + 1 + 3)

Apply FOIL method

(u - 2) (4 u + 1 + 3) : u 4 u + 1 + 3 u - 2 4 u + 1 - 6

= u 4 u + 1 + 3 u - 2 4 u + 1 - 6

(b + b c) (b + b^{^{'}} c) (b + d)

\frac{2 sin ^{2} ( x ) - cos ( x ) ( 1 - 2 cos ( x ) )}{sin ^{2} ( x )}

A (- 2, - 1) B (- 4, 1) c (- 1, 4)

(x + \frac{1}{4}) (x - 5)

(x^{3} + 4 x^{2}) + (3 x^{2} + 12 x) i
