Answer:
Answer: x equals to 2 and -5
Step-by-step explanation:
[tex]{ \tt{ {x}^{2} + 3x - 10 = 0 }}[/tex]
» Factorise the equation quadratically:
[tex]{ \tt{(x - 2)(x + 5) = 0}} \\ { \tt{x = 2 \: \: and \: \: - 5}}[/tex]
This is a polynomial of second class degree. So using quadratic equation
x is 2 and negative 5
