Question

3х2+10х+12=0 ///////////

Answer 1

Ответ:

$3x^2+10x+12 = 0\\D = 100-4*3*12 = 100 -144 = -44\\D < 0$

значит решений нет

Answer 2

To solve the quadratic equation 3x^2 + 10x + 12 = 0, you can use the quadratic formula. The quadratic formula states that for an equation of the form ax^2 + bx + c = 0, the solutions for x can be found using the following formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

For your equation, a = 3, b = 10, and c = 12. Plugging these values into the quadratic formula, we have:

x = (-10 ± √(10^2 - 4312)) / (2*3)

Simplifying further:

x = (-10 ± √(100 - 144)) / 6 x = (-10 ± √(-44)) / 6

Since the square root of a negative number is not a real number, it means that this equation has no real solutions. The graph of the equation would not intersect the x-axis.
