Question

1. Solve by setting the linear factors equal to zero.(x+4)(x-3) = 0
a) x = 4 and x = -3
b) x = 2 and x = 1
c) x = -4 and x = 3
d) x = -2 and x = 1

Answer 1

Answer:

C - x = -4 and x = 3

Step-by-step explanation:

Set (x+4) = 0

x = -4

set (x-3)=0

x=3

Answer 2

Answer:

c) x = -4 and x = 3

Step-by-step explanation:

(x+4)(x-3)=0  

x+4=0 ( You want to find the x value, so we subtract 4 for both sides to get rid of +4)

x +4 -4 = 0 -4

x = -4

x-3=0 ( The same thing, but add 3 either side to get rid of -3 )

x-3 +3 = 0+3

x= 3
