Answer 2

Answer:

Solution of Q. No. 10:

Step-by-step explanation:

If p(x)=4p²-3p+6 then

p(4)=4(4)²-3(4)+6

=4×16-3×4+6

=64-12+6

=58 Ans.

Similarly

P(-5)=4(-5)²-3(-5)+6

=4×25+15+6

=100+15+6

=121 Ans.

Solution of Q.No. 11:

2x²+kx-12

When you put the value of X = 3/2 the value of this polynomial becomes 0.

It means 2×(3/2)² + k×3/2 - 12 = 0

=> 2×9/4 + k×3/2 - 12 = 0

=> 9/2 +k×3/2 - 12 = 0

=> (3/2)K = 12-(9/2)

=> (3/2)k = (24-9)/2

=> 3k = 15

=> K=5 Ans.

Solution of QNo. 12:

4x²+20x+43

_______________

X-3 I 4x³+8x²-17x+10

(-) 4x³-12x²

__________

20x²-17x

(-) 20x²-60x

_____________

43x + 10

( -) the remainder will be 139.
