If 3x-2 is the factor of 3x^3+x^2-22x+12 find other factors

Answer»

SOLUTION ☺️

Let p(X)= 3x^3+x^2-22x+12

So,

=)3x-2= 0

=)3x=2

=)x= 2/3

Putting the value of x= 2/3 in p(x)

p( \frac{2}{3})  = 3 (\frac{2}{3} ) {}^{3}  + ( \frac{2}{3} ) {}^{2}  - 22( \frac{2}{3} ) + 12 \\  =  >  \frac{8}{9}  +  \frac{4}{9}  -  \frac{44}{3}  + 12 \\  =  >  \frac{8 + 4 - 132 + 108}{9}  \\  =  >  \frac{12 - 24}{9}  \\  =  > -  \frac{12}{9}  \\  =  >  -  \frac{4}{3}  \\  =  > other \: factor \:  = 3x + 4

If the p(x) = x^4-2x^3 +3x^2-ax+8 is divided by(x-2) it leaves a remainder 10 find the value of a

Answer»

Step-by-step explanation:

The given POLYNOMIAL is p(x) = x^ 4 – 2x^ 3 + 3x ^2 – ax +8

Given, the polynomial p(x) when divided by (x -2) LEAVES remainder 10.

∴ p(2) = 10 (Remainder Theorem)

⇒ (2)^4 –2( 2)^3 + 3 (2)^2 – a(2) + 8=10

⇒ 16 -16+12-2a+8=10

⇒20-2a=10

⇒-2a=10-20

⇒-2a=-10

⇒a=5

the value of a = 5
