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

x=4 and x= - 5

Step-by-step explanation:

In order to solve this we should re-arrange the equation:

This is equal to:

Then we can seperate this into:

So solving for x in both cases we get

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
