please help I will mark you brain list​

Answer 1

Answer:

=4x(5x-4y) -3y(5x-4y)

=20x²-16xy-15xy+12y²

=20x²-31xy+12y²

Answer 2

$\sf\huge\bold{Answer:}$

Given :

• (4x-3y)(5x-4y)

To find :

Polynomial on multiplication of terms

Solution :

$\tt\red{ :⟶ (4x-3y)(5x-4y) }$

$\tt\ ⇒4x(5x-4y)-3y(5x-4y)$

$\tt\ ⇒20x²-16xy-15xy+12y²$

$\tt\ ⇒20x²-31xy+12y²$

$\tt\ ⇒20x²+12y²-31xy$

Let's Know More :-

• The polynomial formed is a quadratic polynomial with two variables
• It is a quadratic polynomial as it has degree ( highest power ) → 2
• The polynomial has two variables namely → x,y
