$5x^2 - 2x - 3$

$5x^2+3x-5x-3$

$x(5x+3)-(5x+3)$

$(5x+3)(x-1)$

Factoring is the only solution.

Answer:

The answer is "7".

Step-by-step explanation:

Given values:

$\ bag \ of \ rice= 17\frac{1}{2} \\\\\ eating \ rice \ by \ ken \ per \ day = 2\frac{1}{2}\\\\\ rice = \frac{35}{2}\\\\ \ eat \ by \ day = \frac{5}{2}\\\\\ total \ days = \frac{\ bag \ value}{ \ eat \ by \ day}\\\\\ total \ days = \frac{\frac{35}{2}}{\frac{5}{2}}\\\\\ total \ days = \frac{35}{2} \times \frac{2}{5}\\\\\ total \ days = 7$
