Question

X^2+3x-10 will be zero when x equals

Answer 1

This is a polynomial of second class degree. So using quadratic equation

x is 2 and negative 5

Answer 2

Answer: x equals to 2 and -5

Explanation:

`{ \tt{ {x}^(2) + 3x - 10 = 0 }}`

» Factorise the equation quadratically:

`{ \tt{(x - 2)(x + 5) = 0}} \\ { \tt{x = 2 \: \: and \: \: - 5}}`
