Question

.
. Multiply : (3y² + y2 - 2y + 3) by (4y - 5)
​

Answer 1

Answer:

4xy(3y²+5y-7) + 2(y³-4y²+5)

= (12xy³ + 20xy² -28xy ) + ( 2y³ -8y² +10)

=( 2y³ -8y² + 12xy³ + 20xy² -28xy +10) answer

Answer 2

Answer:

( 2y³ - 8y² + 12xy³ + 28xy² - 28xy + 10 )

Step-by-step explanation:

4xy( 3y² + 5y - 7 ) + 2( y³ - 4y² + 5)

= ( 12xy³ + 12xy² - 28xy ) + ( 2y³ - 8y² + 10 )

= ( 2y³ - 8y² + 12xy³ + 28xy² - 28xy + 10 )
