expand (sin(x)+cos(e)x)^2

expand

(sin (x) + cos (e) x)^{2}

sin^{2} (x) + 2 cos (e) x sin (x) + cos^{2} (e) x^{2}

Solution steps

(sin (x) + cos (e) x)^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

a = sin (x), b = cos (e) x

= sin^{2} (x) + 2 sin (x) cos (e) x + (cos (e) x)^{2}

Apply exponent rule:

(a \cdot b)^{n} = a^{n} b^{n}

= sin^{2} (x) + 2 cos (e) x sin (x) + cos^{2} (e) x^{2}

2 (x - 3 = \frac{1}{2} (4 x - 12))

(1, - 1, 1) x (1, 1, - 1)

f (x) = (x + 2)^{24}

\frac{3 ( x ^{2} - 5 x ) + 2}{2}

2 (x^{2} - 3 x + 8)^{2}
