Answer 1

Answer: -9/4

Step-by-step explanation:

Substitute -1/2 in equation and u will get the k

Answer 2

Answer:

Q.1 p(-1/2)=3/4-k-3

➡️ 0=3/4-k-3 ➡️k=(3-12)/4

➡️k= -9/4

Q.2 p(1)= a+a+3=2a+3

➡️2a+3=0 ➡️2a= -3. ...1

q(1)= 1+1+b=2+b

➡️2+b=0 ➡️b= -2. ...2

Multiply equations 1 and 2

2ab=6. ➡️ A b = 3

Q.3 p(-4)=16 + 4 - 2 k - 2

➡️ 0= 18 - 2K ➡️ k = 9

Q.4 g(-4)=16 + 8 - 7p - 3

➡️ 0 = 21 - 7p ➡️ p = 3

Q.5 p(1)=a - 3a + 3 - 1

➡️ 0 = - 2a + 2 ➡️a= 1

Q.6 p(-2)=4 + 4 + 8=16

Since the reminder is not zero, therefore - 2 is not the zero OR root of the equation given.

Q.7 p(-4)=32 - 21 - 12 = 0

Since the remainder is 0, -4 is the solution of the equation given.

Q.8 p(-3)=9 - 18 + 9= 0. Hence the given equation has one root as - 3.
