simplify 5(4x^2+(-2)x+(-6))

simplify

5 (4 x^{2} + (- 2) x + (- 6))

20 x^{2} - 10 x - 30

Solution steps

5 (4 x^{2} + (- 2) x + (- 6))

Simplify

4 x^{2} + (- 2) x + (- 6) : 4 x^{2} - 2 x - 6

= 5 (4 x^{2} - 2 x - 6)

Apply the distributive law:

m (a + b + c) = ma + mb + m c

5 (4 x^{2} - 2 x - 6) = 5 \cdot 4 x^{2} + 5 (- 2 x) + 5 (- 6)

= 5 \cdot 4 x^{2} + 5 (- 2 x) + 5 (- 6)

Simplify

5 \cdot 4 x^{2} + 5 (- 2 x) + 5 (- 6) : 20 x^{2} - 10 x - 30

= 20 x^{2} - 10 x - 30

\frac{( 30 + x )}{2} \cdot \frac{( 119 + 124 )}{2}

10 c^{4} \cdot (0.08)^{4} (1 - 0.08)^{10 - 4}

(3 n - 1) (2 n - 1) (2 n + 1)

(2 - x) (2 + x) (4 + x^{2})

(x^{8})^{3}
