Question

simplify the following expression (-3y+6)(7y-2)​

Answer 1

Answer:

(-3y + 6) ( 7y - 2)

= - 21y + 6y + 42 y - 12

= 21 y + 6y - 12

= 27 y - 12

= 3( 9y - 4) Ans.

Answer 2

Answer:

$- 3y(7y - 2) + 6(7y - 2)$

$- 21y {}^{2} + 6y + 42y - 12$

$- 21y { }^{2} + 48y - 12$

sine change;

$21y {}^{2} - 48y + 12 = 0$
