What is the answer to this math equation(x+5)(x²-3x)​
Nikolay [14]

Answer:

x=-5\\x=0\\x=3

Step-by-step explanation:

I assume your equation to solve is

(x+5)(x^2-3x)=0

When we have a product of two factors equal to zero,

A\cdot B = 0

The solution is either A = 0 or B = 0.

In this case, this means that we can break the equation into two equations:

x+5=0\\x^2-3x=0

Solving the first one, we get:

x+5=0 \rightarrow x = -5

For the second one, we rewrite it as:

x^2-3x=0\\x(x-3)=0

And we see that this equation has two solutions:

x=0\\x=3

Therefore, the three solutions are:

x=-5\\x=0\\x=3
