simplify 9(x-1/3)^2

Solution

simplify

9 (x - \frac{1}{3})^{2}

Solution

(3 x - 1)^{2}

Solution steps

9 (x - \frac{1}{3})^{2}

Simplify

x - \frac{1}{3} : \frac{3 x - 1}{3}

= 9 (\frac{3 x - 1}{3})^{2}

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

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

= 9 \cdot \frac{( 3 x - 1 ) ^{2}}{3 ^{2}}

3^{2} = 9

= 9 \cdot \frac{( 3 x - 1 ) ^{2}}{9}

Cross-cancel common factor:

9

= (3 x - 1)^{2}
