Question

$$\left. \begin{array} { l } { x = - 7 \quad 0 \quad a } \\ { ( x - 8 x ) ( x - 1 ) ( m - 7 ) } \end{array} \right.$$

Answer

X=14*a*x*(x-1)*(m-7)

Solution


Simplify  \(x-3x\)  to  \(-2x\).
\[X=-7a\times -2x(x-1)(m-7)\]
Simplify  \(7a\times -2x(x-1)(m-7)\)  to  \(-14ax(x-1)(m-7)\).
\[X=-(-14ax(x-1)(m-7))\]
Remove parentheses.
\[X=14ax(x-1)(m-7)\]
