Question

X^2+12x+36 решите уравнение

Answer 1

$x^{2} +12x+36=0$

$D = 12^{2} -4*1*36 =144-144=0$

$x=\frac{-12}{2*1} = -6$

Ответ: -6

Answer 3

To solve the equation x^2 + 12x + 36 = 0, we can use factoring since it is a quadratic equation.

The given equation is already in the form of ax^2 + bx + c = 0, where a = 1, b = 12, and c = 36.

Step 1: Try to factor the quadratic expression.

The equation x^2 + 12x + 36 can be factored as (x + 6)(x + 6) because both 6 and 6 add up to 12, and when multiplied together, they give 36.

Step 2: Set each factor equal to zero and solve for x.

(x + 6)(x + 6) = 0

Now, set each factor equal to zero:

x + 6 = 0

Step 3: Solve for x:

x = -6

Step 4: Check the solution:

Plug the value of x back into the original equation:

(-6)^2 + 12(-6) + 36 = 0

36 - 72 + 36 = 0

0 = 0

The equation is satisfied, and therefore the solution x = -6 is correct.

So, the solution to the equation x^2 + 12x + 36 = 0 is x = -6.
