Answer 1

Answer:

Sal solves the equation (x+3)²-4=0 and finds the x-intercepts of f(x)=(x-2)²-9. ... So, would there be an ...

Step-by-step explanation:

Answer 2

Answer:

Roots are (3,-1)

Step-by-step explanation:

x²-2x-3=0

⇒x²-3x+x-3

⇒x(x-3)+1(x-3)

⇒(x+1)(x-3)=0

⇒x+1=0.            OR.   x-3=0

⇒x=-1.               OR.   x=3
