Question

P of X equal to 2 x cube minus 3 X square + 4 x + 5 gfx equal to X + 2

Answer 1

Answer:

Step-by-step explanation:

Given that p(x)=2x^3-3x^2+4x+5

                 g(x)=x+2

                 g(x)=0

then x+2=0

       x=-2

now putting the value of x

So,

$p(-2)=2 * (-2)^3 - 3 * (-2)^2 +4* (-2)+5$

p(-2)=2 x (-8) - 3 x 4 - 8 + 5 (-2^3 converted into -8 as we know that odd power gives minus result and -2^2 converted into 4 as even power gives positive result always)

then

p(-2)=-16-12-8+5

p(-2)=-36+5

p(-2)=-29

So,

x+2 is neither a zero nor a factor of x.

Hope,it helps.
