Question

Expand and Simplify :

(5y-1) (y-2)
​

Answer 1

Step-by-step explanation:

(5y - 1) (y - 2)

5y² - 10y - y + 2

5y² - 11y + 2

5y² - y - 10y + 2

y(5y - 1) - 2(5y - 1)

(y - 2) (5y - 1)

Answer 2

$= (5y-1) (y-2)$

$= 5(y - 2) - 1(y - 2)$

$= 5y - 10 - y + 2$

$= 5y - y - 10 + 2$

$= 4y - 8$

$4y - 8 = 0$

$4y = 8$

$y = \frac{8}{4}$

$y = 2$
