solve this equation pls and explain how do you factor the x
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
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)
Thanks for using Brainly.
