Question

a quadratic polynomial whose zeroes are-2 and 5​

Answer 1

Answer:

= k ( x² + 2x + 5 )

is the answer

+2x because -(-2x)

Answer 2

Answer:

$the \: required \: p(x) = {x}^{2} - 3x - 10 \\ clearly \: \\ sum \: of \: zeroes \: = \alpha + \beta \\ \frac{ - b}{a} = - 2 + 5 = 3 \\ prduct \: of \: zeroes \: = \alpha \beta \\ \frac{c}{a} = - 2 \times 5 = - 10 \\ hence \\ \: p(x) = {x}^{2} - 3x - 10$
