Question

if A and B are the zeros of x square + 9 X + 7 then the value of a + b is​

Answer 1

$\tt \huge \underline{answer}$

• A and B are the zeroes of quadratic equation

• Given equation: x²+9x+7

Solution:-

we know that

General Formula of quadratic equations....

$\sf \huge\boxed{ {ax}^{2} + bx + c = 0}$

Let us compare the given equation with standard form of quadratic equations.

• a=1

• b=9

• c=7

A+B=-b/a=-9/1=-9

therefore,

$\tt \bigstar \boxed { \: \: a + b = - 9 \: \: }$

Answer 2

Answer:

the answer of your question is-9
