1. Choose 2 integers. Then write an equation with those roots in standard form. how would the equation change if the signs of the 2 roots were switched. 2. Explain why you can't solve x(x+5) = 24 by solving x = 24 and x + 5 = 24

1.

Let the integers be 3 and -6

x2+3x-18=0

If the signs are switched

The numbers are -3 and 6

x2-3x-18=0

2. 

x(x+5) =24

Right hand side is not zero but 24

So we cannot write x=24 or x+5 =24

X2+5x-24=0

X2+8x-3x-24=0

X(x+8)-39X=8)=0

(x+8)(x-3)=0

Since RHS = 0, we can write

X= -8 or x =3
