(2 + x 2)^{2}

4 + 42 x + 2 x^{2}

Solution steps

(2 + x 2)^{2}

Apply Perfect Square Formula:

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

(2 + x 2)^{2} = 2^{2} + 2 \cdot 2 x 2 + (x 2)^{2}

= 2^{2} + 2 \cdot 2 x 2 + (x 2)^{2}

2^{2} = 4

2 \cdot 2 x 2 = 42 x

(x 2)^{2} = 2 x^{2}

= 4 + 42 x + 2 x^{2}

(1 - sin (a))^{2} + (cos (a))^{2}
