$$[ \frac { 3 } { 4 } \cdot 0.001 t ^ { 4 } - \frac { 1 } { 3 } \cdot 0.01 t ^ { 3 } - \frac { 1 } { 2 } 0.3 t ^ { 2 } + 4 t ] _ { 0 } ^ { 12 }$$

Evalwa

$$\frac{3t^{4}}{4000}-\frac{t^{3}}{300}-\frac{3t^{2}}{20}+4t$$

Passi tas-Soluzzjonijiet

Immultiplika \frac{3}{4} u 0.001 biex tikseb \frac{3}{4000}.

$$\frac{3}{4000}t^{4}-\frac{1}{3}\times 0.01t^{3}-\frac{1}{2}\times 0.3t^{2}+4t$$

Immultiplika \frac{1}{3} u 0.01 biex tikseb \frac{1}{300}.

$$\frac{3}{4000}t^{4}-\frac{1}{300}t^{3}-\frac{1}{2}\times 0.3t^{2}+4t$$

Immultiplika \frac{1}{2} u 0.3 biex tikseb \frac{3}{20}.

$$\frac{3}{4000}t^{4}-\frac{1}{300}t^{3}-\frac{3}{20}t^{2}+4t$$

Fattur

$$\frac{t\left(9t^{3}-40t^{2}-1800t+48000\right)}{12000}$$

Passi tas-Soluzzjonijiet

Immultiplika \frac{3}{4} u 0.001 biex tikseb \frac{3}{4000}.

$$factor(\frac{3}{4000}t^{4}-\frac{1}{3}\times 0.01t^{3}-\frac{1}{2}\times 0.3t^{2}+4t)$$

Immultiplika \frac{1}{3} u 0.01 biex tikseb \frac{1}{300}.

$$factor(\frac{3}{4000}t^{4}-\frac{1}{300}t^{3}-\frac{1}{2}\times 0.3t^{2}+4t)$$

Immultiplika \frac{1}{2} u 0.3 biex tikseb \frac{3}{20}.

$$factor(\frac{3}{4000}t^{4}-\frac{1}{300}t^{3}-\frac{3}{20}t^{2}+4t)$$

Iffattura 'l barra \frac{1}{12000}.

$$\frac{9t^{4}-40t^{3}-1800t^{2}+48000t}{12000}$$

Ikkunsidra li 9t^{4}-40t^{3}-1800t^{2}+48000t. Iffattura 'l barra t.

$$t\left(9t^{3}-40t^{2}-1800t+48000\right)$$

Erġa' ikteb l-espressjoni ffatturata kompluta. Polynomial 9t^{3}-40t^{2}-1800t+48000 mhux fatturat billi m'għandux għeruq razzjonali.

$$\frac{t\left(9t^{3}-40t^{2}-1800t+48000\right)}{12000}$$
