Question

In the polynomial P(x) = 2x³-3x²-7x +3
and P(-1),P(2),P(0)P(-2). which of these is
the largest​

Answer 1

Answer:

if x= 1 is root then when we put this value in given polynomial we must get 0 . therefore

2x³ -3x² +7x -6

so we put x = 1

2×1³ -3×1²+7×1 -6

2-3+7-6= 0

yes x= 1 is root of given polynomial
