Question

Verify that :- 1 and 2 are the zeros of the polynomial p(x) = (x - 1) (x - 2).please answer me fast!!!!!!! guys....the zero of the polynomial p(x) =x-1 is 1

Answer 1

$Given \: polynomial \: p(x) = (x-1)(x-2)$

$i) If \: x = 1 \: then \: p(1) = (1-1)(1-2) \\= 0 \times (-1) \\= 0$

$p(1) = 0$

Therefore.,

$1 \: is \: a \: zero \: of \: p(x)$

$ii) If \: x = 2 \: then \: p(2) = (2-1)(2-2) \\= 1 \times 0 \\= 0$

$p(2) = 0$

Therefore.,

$2\: is \: a \: zero \: of \: p(x)$

___________

$Given \: p(x) = x - 1$

$If \: x = 1 \: then \: p(1) = 1 - 1 = 0$

$p(1) = 0$

$\therefore 1 \:is \: a \: zero \: of \: p(x)$
