Question

СРОЧНО ПОМОГИТЕ СРОЧНО x²-x-6=0

Answer 1

Ответ:

x^2 - x - 6 = 0

D = 1 + 4*6 = 25

x1 = ( 1 + 5)/2 = 6/2 = 3;

x2 = ( 1 -  5)/2 = - 4/2 = - 2

Объяснение:

Answer 2

I can help you solve this equation by factoring. Here are the steps:

- First, we need to find two numbers that multiply to -6 and add to -1. These numbers are -3 and 2. - Next, we can rewrite the equation as x²-3x+2x-6=0 and then group the terms by parentheses: (x²-3x)+(2x-6)=0 - Then, we can factor out the common factors from each group: x(x-3)+2(x-3)=0 - Now, we can use the distributive property to write the equation as (x+2)(x-3)=0 - Finally, we can set each factor equal to zero and solve for x: x+2=0 or x-3=0. The solutions are x=-2 or x=3.

You can check your answer by plugging in the values of x into the original equation and see if they make it true.
