Question

What is the polynomial equation of +2,+7

Answer 1

${x}^{2} - 9x + 14$

Step-by-step explanation:

$Given, \: \: let \: \: \alpha = 2 \: \: and \: \: \beta = 7 \\ we \: \: know \: \: \\ General \: \: form \: \: of \: \: quadratic \: \: equation \\ \boxed{ {x}^{2} - ( \alpha + \beta )x + \alpha \beta } \\ putting \: \: values \\ {x}^{2} - (2 + 7)x + 2 \times 7 \\ {x}^{2} - 9x + 14$
