Question

एक द्विघात बहुपद लिखिए जिसके बहुपद के शून्यको का योग - 3 और गुणनफल - 10 है ​

Answer 1

Answer:

${x}^{2} + 3x - 10 = 0$

because,

$a {x}^{2} + bx + c = 0$

=> x^2 + b/a x + c/a =0 ...........(1)

we know that,

शुन्यको का योग = -b/a = -3 .........(2)

=> b/a = 3

शुन्यको का गुणनफल = c/a = -10 .........(3)

then, by equation (1) , (2) and (3) =>

x^2 + 3x - 10 = 0 ANSWER
