Question

DIVIDE POLYNOMIALS USING LONG DIVISION
(y2 + 4y – 21) ÷ (y +7)
(x2 – 3x + 5) ÷ (x – 4)
(6x2 + 7xy – 20y2) ÷ (2x + 5y)
WITH SOLUTION PLS

Answer 1

Answer:

(y2 + 4y – 21) ÷ (y +7)

solution,

here,

y+7)y2 + 4y – 21( y - 11

y2 +7y

- -

-11y - 21

-11y - 77

+ +

56

so, Q(x) = y - 11

R = 56

x2 – 3x + 5) ÷ (x – 4)

solution,

here,

x-4) x2 + 3x– 5 ( x+7

x2 - 4x

- +

7x - 5

7x - 28

+ +

23

so, Q(x) = x+7

R = 23

hope it helps you
