4. ച ോദ്യം
1.p(x) = x+ 1
q(x) = 2x
p(x)q(x) =?

5. ഉത്തരം
P(x) = x+1
q(x) = 2x
P(x)q(x) = (x+1) 2x
= 2x * x + (2x * 1)
= 2x^2 + 2x

6. ച ോദയം
P(x) = 3x^2 + 5x-7
q(x) = x^2 – 7x + 2
P(x)q(x) = ?

7. ഉത്തരം
P(x) = 3x^2 +5x -7
q(x)= x^2- 7x +2
P(x)q(x)=(3x^2 +5x – 7)(x^2-7x +2)
=3x^2 * x^2 + 3x^2 * (-7x) + 3x^2 * 2 + 5x *x^2 + 5x *(-7x) + 5x *2 + (-7x) *x^2
+ (-7) *(-7x) + (-7) * 2
= 3x^4 -2x^3 + 6x^2 + 5x^3 -35x^2 + 10x -7x^2 +49 x-14
= 3x^4 -21x^3 +5x^3 + 6x^2 – 35x^2 – 7x^2 +10x + 49x -14
= 3x^4 – 16 x^3 – 36x^2 +59x -14

8. HOME WORK
p(x) = 2x^2 +3x+1
q(x) = 4x+5
P(x)q(x) = ?
