Question

Find the product: (x^4-3/5 x^3+1/2 x^2-x+1) (3x^3+ 7/2 x^2 +5/3 x - 10/9)​

Answer 1

Answer:

Disclaimer: There is error in the Q. In (II) there should have been 2x - 3y = 12

5x + 3y = 9 -----(I)

2x - 3y = 12 ----- (II)

Add (I) and (II)

7x = 21

x = 3

Putting the value of x = 3 in (I) we get

5(3)+3y=9⇒15+3y=9⇒3y=9-15=-6⇒y=-2

Thus, (x, y) = (3, -6).
