Question

The sum of the zeroes : 5 x^2 + 10x + 7 is -1/2... Is it true or false? And true then how?​

Answer 1

Answer:

False

Step-by-step explanation:

$for\\ax^2+bx+c=0\\\\if \;\;\alpha\;and\;\beta\;are\;the\;roots\;then\\\\\alpha+\beta=-\frac{b}{a}\\\\and\\\\\alpha\beta=\frac{c}{a}\\\\Now\;\; Here\\\\a=5\;\;\;b=10\;\;and\;\;c=7\\\\Then\\\\\alpha+\beta=-\frac{10}{5}=-2$

Hope it Helps

Answer 2
