simplify (2-sqrt(2))(2-sqrt(2))

simplify

(2 - 2) (2 - 2)

6 - 42

Decimal Notation

0.34314 \dots

Solution steps

(2 - 2) (2 - 2)

Apply exponent rule:

aa = a^{2}

(2 - 2) (2 - 2) = (2 - 2)^{2}

= (2 - 2)^{2}

Apply Perfect Square Formula:

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

(2 - 2)^{2} = 2^{2} - 2 \cdot 22 + (2)^{2}

= 2^{2} - 2 \cdot 22 + (2)^{2}

2^{2} - 2 \cdot 22 + (2)^{2} = 6 - 42

= 6 - 42
