Question

A: What are the solutions to the quadratic equation?

B: which statements accurately interpret the solution?

Answer 1

A. x = -1 or x = 3

B. first

Explanation:

`x^2-2x-3=0\\\\x^2+x-3x-3=0\\\\x(x+1)-3(x+1)=0\\\\(x+1)(x-3)=0\iff x+1=0\ \vee\ x-3=0\\\\x+1=0\qquad\text{subtract 1 from both sides}\\x=-1\\\\x-3=0\qquad\text{add 3 to both sides}\\x=3`
