Question

Find the quadratic polynomial whose zeroes are -2 and -5

Answer 1

Answer:

Quadratic Formula =

${x}^{2} - x( \alpha + \beta ) + \alpha \beta$

Here

$\alpha = - 2 \: and \: \beta = - 5$

Now insert the values.

${x}^{2} - x( - 2 + ( - 5) + ( - 2)( - 5)$

${x}^{2} - x( - 2 - 5) + 10$

${x}^{2} - x( - 6) + 10$

${x}^{2} + 6x + 10$

☆ X^2 + 6X + 10 is required quadratic polynomial.
