Question

Write quadratic polynomial , the sum of whose zero is -5 and their products is 6



plz answer fast do​

Answer 1

Answer:

x^2-5x-6

Step-by-step explanation:

formula is =x^2+(a+b)x-ab.

put the value that are given in your question.

a+b=-5.

ab=6

are given

Answer 2

$\large\bf\underline\red{Answer \: :-}$

Given that :

• $\sf{ \alpha + \beta = - 5}$
• $\sf{ \alpha \beta = 6}$

Now,

We know that,

$\sf\bigstar{\:f(x) = x {}^{2} - ( \alpha + \beta ) x+ \alpha \beta }$

Now put the values

$\sf\longmapsto{f(x) = x {}^{2} - ( -5)x + 6} \\ \\ \sf\longmapsto{f(x) = x {}^{2} + 5x + 6 } \: \: \: \: \: \: \:$

The Quadratic polynomial is x² + 5x + 6.
