Question

Розв'яжи рівняння: x^2+22x−3=0 срочно!!!

Answer 1

Ответ:

-11±2√31

Пошаговое объяснение:

x² + 22x - 3 = 0

a=1; b=22; c= -3

D=b²-4ac= 22²-4*1*(-3)= 484+12=496

√496 = √(16*31) = 4√31

x = (-b±√D)/2a

x1 = (-22-4√31)/2 = -11-2√31

x2= (-22+4√31)/2 = -11+2√31

Answer 2

Solving the Equation: x^2 + 22x - 3 = 0

To solve the equation x^2 + 22x - 3 = 0, 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 = (-b ± √(b^2 - 4ac)) / (2a)

In our case, the coefficients are: - a = 1 - b = 22 - c = -3

Plugging these values into the quadratic formula, we get:

x = (-22 ± √(22^2 - 4 * 1 * -3)) / (2 * 1)

Simplifying further:

x = (-22 ± √(484 + 12)) / 2

x = (-22 ± √496) / 2

Now, let's calculate the solutions using the quadratic formula:

x = (-22 + √496) / 2 and x = (-22 - √496) / 2

Calculating the values:

x = (-22 + √496) / 2 ≈ 0.0707 and x = (-22 - √496) / 2 ≈ -22.0707

Therefore, the solutions to the equation x^2 + 22x - 3 = 0 are approximately x ≈ 0.0707 and x ≈ -22.0707.
