Question

find the domain of
$x ^{2} + 5x - 6$
​

Answer 1

$\huge\rm\underline\purple{ANSWER:-}$

The domain of the expression is all real numbers except where the expression is undefined.

$\rm ⟹ F(x)=√(x−2)(x−3)$

• Assuming F:R→R , we know that

$\rm →(x−2)(x−3)≥0$

Consider x<2 : we have (negative)(negative)=positive≥0
