Question

Which value of x makes the expression x2-9/x2+7x+10? undefined?

Answer 1

The expression is undefined when the denominator cannot equal to zero, so you have to solve the equation: \[x^2+7x+10\neq0\]

Answer 2

@purplec16 idk how to, i dont understand it at all

Answer 3

What exactly don't you understand what makes it undefined or how to solve, and you would solve it just like how you solve an equation don't let the not equal to sign confuse you

Answer 4

\[(x+2)(x+5)\neq0\]\[(x+2)\neq0\]\[x\neq-2\]\[(x+5)\neq0\]\[x\neq-5\]

Answer 5
