Answer: The required simplified product is \(-45x+18x^2.\)
Step-by-step explanation: We are given to find the following product :
\(P=-9x(5-2x)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\)
We will be using the following property of distribution over addition to solve our problem :
\(a\times(b+c)=a\times b+a\times c.\)
From equation (i), we have
\(P\\\\=-9x(5-2x)\\\\=-9x\times5+(-9x)\times(-2x)\\\\=-45x+18x^2.\)
Thus, the required simplified product is \(-45x+18x^2.\)
