Question

check that the 2 is the factor of 3y ³+4y²-5y +2​

Answer 1

Answer:

f(y)=3y³+4y²-5y+2.

f(2)=3(2³)+4(2²)-5(2)+2

=3(8)+4(4)-5(2)+2

=24+16-10+2

=42-10

f(2)=32.

here f(2) is 32. to prove that 2 is a factor, f(2) must be 0 but here it is different.i.e,32 is not equal to 0.

SO 2 IS NOT A FACTOR
