factor cos^2(y)+2cos(y)+1

factor

cos^{2} (y) + 2 cos (y) + 1

(cos (y) + 1)^{2}

Solution steps

cos^{2} (y) + 2 cos (y) + 1

Rewrite

cos^{2} (y) + 2 cos (y) + 1

cos^{2} (y) + 2 cos (y) \cdot 1 + 1^{2}

= cos^{2} (y) + 2 cos (y) \cdot 1 + 1^{2}

Apply Perfect Square Formula:

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

a = cos (y), b = 1

= (cos (y) + 1)^{2}

0.080645 (4 t + 8)^{3.1} + C

t r in o mia l - 5^{2} + x + 4
