Question

quadratic equation x^2+2x+24. please solve for x.​

Answer 1

Step-by-step explanation:

When looking to factor a trinomial of the form y = ax2 + bx + c, where a = 1, you must find two numbers that multiply to c and that add to b.

The two numbers we are looking for are 6 and -4, since 6 X -4 = -24 and 6 + (-4) = 2

x2 + 2x - 24 = 0

(x +6)(x - 4) = 0

x = -6 and 4

The solutions are -6 and 4.

Answer 2

Answer:

${x}^{2} + 2x + 24 = 0$

$x = \frac{ - 2 + \sqrt{ {2}^{2} - 4.1.24} }{2.1} \\ or \\ x = \frac{ - 2 - \sqrt{ {2}^{2} - 4.1.24} }{2.1}$

$x = - 1 + i \sqrt{23} \: or \: - 1 - i \sqrt{23}$
