How to factor 4(x+5)^3(x-1)^2-(x+5)^4 • 2 (x-1) by grouping?
nata0808 [166]
\bf 4(x+5)^3(x-1)^2-(x+5)^4\cdot 2(x-1)
\\\\\\
4(x+5)^3(x-1)^2-2(x-1)(x+5)^4
\\\\\\ \underline{2}\cdot 2\underline{(x+5)^3}(x-1)\underline{(x-1)}~-~\underline{2}\underline{(x-1)}(x+5)\underline{(x+5)^3}\leftarrow 
\begin{array}{llll}
notice~the\\
common\\ \underline{factors}
\end{array}
\\\\\\
2(x+5)^3(x-1)~[~2(x-1)-(x+5)~]
\\\\\\
2(x+5)^3(x-1)~[2x-2-x-5]\implies 2(x+5)^3(x-1)(x-7)

90% of a number is x . What is 100% of the number? Assume x>0
mariarad [96]

Step-by-step explanation:

Let the required number be n

\therefore \:  \frac{90}{100}  \times n = x \\  \\ \therefore \:  \frac{9}{10}   \\  \\  \therefore \:n = \frac{10}{9} x \\  \\  \therefore 100\% \: of\:n = \frac{10}{9} x \times 100\% \\  \\  = \frac{10}{9} x \times \frac{100}{100}  \\  \\  =  \frac{10}{9} x  \\

NOTE: A number is always 100% in itself.
