Question

What are the solutions to the equation 3(x – 4)(x + 5) = 0?
x = –4 or x = 5
x = 3, x = 4, or x = –5
x = 3, x = –4, or x = 5
x = 4 or x = –5

Answer 1

Answer:

x=4

x= -5

..............

Answer 2

Step-by-step explanation:

3(x-4)(x+5)=0

or,3(x^2+5x-4x-20)=0

or,x^2+x-20=0

or,x^2+5x-4x-20=0

or,x(x+5)-4(x+5)=0

or,x=-5,4

fouth option is the correct one.......
