Question

3.
The quadratic polynomial, the sum of whose zeroes is -5 and their product is
6, is
(a) *? +5r+6 (b) x2-5r+6 (c) x² – 5x - 6 (d) - x2 + 5x + 6​

Answer 1

$\bf\huge{\underline{\pink{ANSWER}}}$

$\alpha + \beta = - 5$

$\alpha . \beta = 6$

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

$= {x}^{2} - ( -5)x + 6$

$= {x}^{2} + 5x + 6$
