Question

Check whether 3 and -2 are zeros of the polynomials x² - 5x+6​

Answer 1

Answer:

3 is a zero but isnt.

Step-by-step explanation:

U put the value of 3 in the place of x

you'll get ,

(3)²-5(3)+6

9-15+6

=0

Therefore, 3 is a zero of the given polynomial.

If u try for -2 it is not possible.

Thank u for asking and sharing

ur doubt.

Answer 2

Answer:

No, The Zeros of the polynomial are 2 (or) 3.

Step-by-step explanation:

Given Equation : $x^{2} -5x+6$

By factorisation method :

⇒$x^{2}-5x+6$

Multiply last and first term to segregate the middle term.

⇒$6=2*3$

⇒$x^{2} -2x-3x+6$

⇒$x(x-2)-3(x-2)$

⇒$(x-2)(x-3)$

⇒$x=2,3$

The value of x is 2 (or) 3.
