expand 12(-0.5)^2+12(-0.5)

expand

12 (- 0.5)^{2} + 12 (- 0.5)

- 3

Solution steps

12 (- 0.5)^{2} + 12 (- 0.5)

Remove parentheses:

(- a) = - a

= 12 (- 0.5)^{2} - 12 \cdot 0.5

(- 0.5)^{2} = 0. 5^{2}

= 12 \cdot 0. 5^{2} - 12 \cdot 0.5

Multiply the numbers:

12 \cdot 0.5 = 6

= 12 \cdot 0. 5^{2} - 6

12 \cdot 0. 5^{2} = 3

= 3 - 6

Subtract the numbers:

3 - 6 = - 3

= - 3

2 (x + π y)^{5}

(1 + e^{x}) e^{2 x}

\frac{( k + 1 ) ^{2} ( k + 2 ) ^{2} ( 2 k ^{2} + 6 k + 3 )}{12}

\frac{2 π ( 7 17 + 1 )}{3}

\frac{\frac{d}{d x} ( ( 3 x ^{2} + 9 ) ( 5 x - 3 ) )}{6 x - 7}
