## How to solve x4-2×3-9×2+5x+3 untuk x=4

First of all write this question properly,

\displaystyle {{\mathbf{x}}^{4}}-\mathbf{2}{{\mathbf{x}}^{3}}-\mathbf{9}{{\mathbf{x}}^{2}}+\mathbf{5x}+\mathbf{3}

Let putting value of x = 4

\displaystyle {{(4)}^{4}}-\mathbf{2}{{(4)}^{3}}-\mathbf{9}{{(4)}^{2}}+\mathbf{5}(4)+\mathbf{3}

\displaystyle (4\times 4\times 4\times 4)-\mathbf{2}(4\times 4\times 4)-\mathbf{9}(4\times 4)+\mathbf{5}(4)+\mathbf{3}

\displaystyle (16\times 16)-\mathbf{2}(16\times 4)-\mathbf{9}(16)+\mathbf{5}(4)+\mathbf{3}

\displaystyle (256)-\mathbf{2}(64)-\mathbf{9}(16)+\mathbf{5}(4)+\mathbf{3}

\displaystyle 256-128-144+20+\mathbf{3}

\displaystyle 256-128-144+23

\displaystyle 256-372+23

\displaystyle 279-372
