Question

if a and b are roots of the equation x2 + ax + b = 0,then a + b = ?​

Answer 1

Answer:

Hi the answer is -a

Step-by-step explanation:

There is a formula which is

$a + b = \frac{ - coefficient \: of \: x \: term}{coefficient \: of \: {x}^{2} \: term}$

So according to the formula coefficient of

${x}^{2}$

is 1 and coefficient of x term is a

so now the sum of roots= -a/1

So now the answer is -a
