Question

) Verify whether 2 and 3 are the zeroes of the polynomial x2-3x+2 ?




please answer fast I have exam​

Answer 1

Answer:

2 is the zero of polynomial x² + 3x + 2

Step-by-step explanation:

$p(x)= x^{2} -3x+2$

$\\Putting$ $x= 2$

$p (2)= (2) ^{2} -3(2)+2\\ = 4-6+2\\= 4-4\\= 0$

$2$ $is$ $the$ $0$ $of$ $p(x)$.

$Putting$ $x = 3$

$p(3)= (3)^{2} -3(3)+2\\ = 9-9+2\\= 2$

$3$ $is$ $not$ $the$ $0$ $of$ $p(x).$

Answer 2

$\huge\tt\green{Answer}$

${x}^{2} - 3x + 2 = 0 \\ if \: x = 2 \\ {2}^{2} - 3(2) + 2 = 0 \\ 4 - 6 + 2 = 0 \\ if \: \: x = 3 \\ {3}^{2} - 3(3) + 2 = 0 \\ 9 - 9 + 2 \: is \: not \: equal \: to \: 0$
