Question

show that x=1is zero of the polynimial 2x^3-3x^2+7x-6

Answer 1

$p(x) = 2x {}^{3} - 3x {}^{2} + 7x - 6 \\ p(1) = 2 \times 1 {}^{3} - 3 \times1 {}^{2} + 7 \times 1 - 6 \\ = 2 - 3 + 7 - 6 = 9 - 9 = 0$
As, p(1) becomes zero. of p(x).
•°• x=1 is the zero of polynomial.

Answer 2

Heya !!!



X = 1


P(X) = 2X³ - 3X² + 7X -6



P(1) = 2 × (1)³ - 3 × (1)² + 7 × 1 - 6



=> 2 - 3 + 7 -6



=> 9-9


=> 0


Remainder = 0



Hence,


1 is a zero of the given polynomial.
