Answer 1

Answer:

your answer is here buddy...

13) 2 - 20/ 3 = x

-18 / 3 = x

-6 = x

14) 7 - 1 -6 = 0

other zero = 0 & 1

15) you haven't provided the second zero.

16) -ab - b² + p

p = ab + b²

17) your question is not understandable..what is that a--a-2????

18)k =15x² + 14x

19)your question is not in correct form.. which value should we find???

20) your question is incorrect. 1f or if????

21) -1x² + 1/6x + 2 = 0

22)ap + a 3* = 78

23) p = 1/10

24) there is no p' given in the equation only p has given.

25) 1 & - 2

hope this will help you......

Answer 2

Answer:

$\huge\red{\boxed{\sf AnsWeR}}$

Expert Answer:

1. Quotient = 2x - 5, remainder = -5.
2. Verification:
3. It can be seen that:
4. (x + 3) (2x - 5) - 5 = 2x2 + 6x - 5x - 15 - 5 = 2x2 + x - 20.
5. Dividend= Divisor x Quotient + Remainder.
6. Hence, the division algorithm is verified.
