Question

Write a quadratic polynomial sum of whose zeroes is 2 and product is -8 *

1 point

x² - 2x - 8

x² + 2x - 8

x² - 2x - 8 = 0

x² - 6x - 2

​

Answer 1

Answer:

We know,

➡ Formula for forming quadratic equation :

${x}^{2} - (sum \: of \: the \: roots)x + (product \: of \: the \: roots) = 0$

So equation will be :

${x}^{2} - ( - 2)x + ( - 8) = 0\\ \\ = > {x}^{2} + 2x - 8 = 0$

➡ So option ( b ) ✔
