Question

Which polynomial will you get after subtracting (4 + 9y + 2x) from the sum

of (8x – 6y + 4) and (6y – 3x + 7)?

(1) 3x – 9y + 7 (2) 3x – 3y + 7

(3) 7x + 9y + 15 (4) 7x – 9y – 15​

Answer 1

Answer:

(3) 7x+9y+15

Step-by-step explanation:

Sum => (8x-6y+4)+(6y-3x+7)

        => 8x-6y+4+6y-3x+7

        => 8x-3x-6y+6y+4+7

        => 5x+11

Difference => 5x+11+(4+9y+2x)

                  => 5x+11+4+9y+2x

                  => 5x+2x+9y+11+4

                  => 7x+9y+15
