Question

Решить уравнение(х-4)(х+4)=0​

Answer 1

(х-4)(х+4)=0​

х^2-16=0

x^2=16

х1=-4

х2=4

Answer 2

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

1)x-4=0

x=4

2)x+4=0

x=-4

Answer 3

To solve the equation (x-4)(x+4) = 0, we can use the zero-product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be equal to zero.

So, we set each factor equal to zero and solve for x:

1. x - 4 = 0 Add 4 to both sides: x = 4

2. x + 4 = 0 Subtract 4 from both sides: x = -4

Therefore, the solutions to the equation are x = 4 and x = -4.
