Question

find the sum and product of the zero x2-4x+3
​

Answer 1

• Sum = 4

• Product = 3

Step-by-step explanation:

First Lets Calculate The Factor of polynomial :-

${x}^{2} - 4x + 3 \\ = > \bf{by \: mid \: split \: term} \\ = > x {}^{2} - 3x - x + 3 \\ = > x( x - 3) - 1(x - 3) \\ = > (x - 3)(x - 1)$

Thus The Factor are (x-3) & (x-1)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Now Lets Calculate The zero :-

i) x - 3 = 0

=> x = 3

ii) x - 1 = 0

=> x = 1

Thus the zeros 1 & 3

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Sum => 3 + 1 = 4

Prpduct => 3 x 1 = 3
