Question

Solve this equation pls and explain how do you factor the x

Answer 1

Hi there!

I understand your struggles. Don't worry!

First, factor out x from the equation.

x  times (x+7)=0 (Factor is a number that can be multiplied together to get another number)

When the product of factors equals 0, this means one factor is 0.

Therefore:

x=0

x+7=0

Solve the equation for x.

x=0

x=-7

This equation also has two solutions.

x1 = -7 x2= 0

Answer 1: -7

Answer 2: 0

These are our answers.

You mentioned you were confused about factoring.

Let me give you an example of factoring:

Equation: 2y+6

#1: Both 2y and 6 have a common factor of 2.

2y is 2 x y

6 is 2 x 3

Therefore: The expression can be factored to

2y+6=2(y+3)

Answer 2

Answer:

x = - 7, x = 0

Step-by-step explanation:

Given

x² + 7x = 0 ← factor out x from each term on the left side

x(x + 7) = 0

Equate each factor to zero and solve for x

x = 0

x + 7 = 0 ⇒ x = - 7
