Question

X( квадрат)-6x-7=0 помагите. Пожалуйста!

Answer 1

X²-6x-7=0
x1+x2=6 U x1*x2=-7
x1=-1 U x2=7

Answer 2

Solving the Equation

To solve the equation x^2 - 6x - 7 = 0, we can use the quadratic formula or factorization method. Let's use the factorization method.

1. Rewrite the equation in the form of (x - a)(x - b) = 0. - The factors of -7 that add up to -6 are -7 and +1. - So, the equation can be written as (x - 7)(x + 1) = 0.

2. Set each factor equal to zero and solve for x. - (x - 7) = 0 => x = 7 - (x + 1) = 0 => x = -1

Therefore, the solutions to the equation x^2 - 6x - 7 = 0 are x = 7 and x = -1.

Answer

The solutions to the equation x^2 - 6x - 7 = 0 are x = 7 and x = -1.
