Solution steps

(3 - 7) (3 - 7)

Apply exponent rule:

aa = a^{2}

(3 - 7) (3 - 7) = (3 - 7)^{2}

= (3 - 7)^{2}

Apply Perfect Square Formula:

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

(3 - 7)^{2} = 3^{2} - 2 \cdot 37 + (7)^{2}

= 3^{2} - 2 \cdot 37 + (7)^{2}

3^{2} - 2 \cdot 37 + (7)^{2} = 16 - 67

= 16 - 67
