Question

Найди все значениях, при которых выражение равно 0 (х + 8)(х -7) Выражение равно 0 при X =​

Answer 1

При х=-8, при х=7 Вот

Answer 2

Выражение может быть равно 0 только тогда, когда один из его множителей равен 0

Следовательно (х+8)=0 или (х-7)=0

Х+8=0

х= -8

Х-7 = 0

х = 7

Ответ: -8; 7

Answer 3

Solving the Equation (х + 8)(х - 7) = 0

To find the values of x for which the expression (х + 8)(х - 7) equals 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 zero.

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

1. Setting (х + 8) equal to 0: - х + 8 = 0 - х = -8

2. Setting (х - 7) equal to 0: - х - 7 = 0 - х = 7

Therefore, the expression (х + 8)(х - 7) equals 0 when x = -8 or x = 7.
