expand (4k-xm)(kz^2-x(mz^2)/4)

expand

(4 k - x m) (k z^{2} - x \frac{m z ^{2}}{4})

4 k^{2} z^{2} - 2 k x m z^{2} + \frac{x ^{2} m ^{2} z ^{2}}{4}

Solution steps

(4 k - x m) (k z^{2} - x \frac{m z ^{2}}{4})

Apply FOIL method

(4 k - x m) (k z^{2} - x \frac{m z ^{2}}{4}) : 4 k^{2} z^{2} - 2 k x m z^{2} + \frac{x ^{2} m ^{2} z ^{2}}{4}

= 4 k^{2} z^{2} - 2 k x m z^{2} + \frac{x ^{2} m ^{2} z ^{2}}{4}

(\frac{7}{9} + \frac{2}{9})^{9}

\frac{1}{x - 2} - \frac{4}{x ^{2} - 4}

\frac{( 2 + j ) ( 0.6 + j ^{0.8} )}{- 4 + j} - j

lo g_{10} (3) (4 x + 6) - lo g_{3} (3 x + 9)

\frac{1}{4} (- 16 x + 8)
