Question

X^+6x-15=0 aaaaaaaaaaaaaaaaaaaaaaaaa

Answer 1

х + 6х - 15 = 0 ;

7х - 15 = 0 ;

7х = 15

-----------------------------------

х²+6х-15=0;

х²+6х=15;

х²+6х+(6/2)²=15+(6/2)²;

(х+6/2)²=24;

(х+3)²=24;

х=-2√6-3 или 2√6-3

Решение может быть не точным!

Знак "/" - это дробь;

Знак "√" - это корень;

Надеюсь всё понятно...

Answer 2

The equation you provided is a quadratic equation in the form of $x^2 + 6x - 15 = 0$. To solve this equation, we can use the quadratic formula.

The quadratic formula states that for an equation in the form $ax^2 + bx + c = 0$, the solutions for $x$ can be found using the formula:

$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

In this case, $a = 1$, $b = 6$, and $c = -15$. Plugging these values into the quadratic formula, we get:

$x = \frac{-6 \pm \sqrt{6^2 - 4 \cdot 1 \cdot (-15)}}{2 \cdot 1}$

Simplifying further:

$x = \frac{-6 \pm \sqrt{36 + 60}}{2}$

$x = \frac{-6 \pm \sqrt{96}}{2}$

$x = \frac{-6 \pm \sqrt{16 \cdot 6}}{2}$

$x = \frac{-6 \pm 4\sqrt{6}}{2}$

$x = -3 \pm 2\sqrt{6}$

So the solutions to the equation are $x = -3 + 2\sqrt{6}$ and $x = -3 - 2\sqrt{6}$.
