Question

X^2+5x-6=0 ///////help

Answer 1

D = 5² - 4*1*(-6) = 25 + 24 = 49, D > 0,

x1 = (-5 + 7) / 2 = 2/2 = 1.
x2 = (-5 - 7) / 2 = -12 / 2 = -6.

Answer 2

Sure, I can help you solve the quadratic equation X^2 + 5x - 6 = 0. To find the solutions for X, we can use the quadratic formula:

The quadratic formula is given by:

X = (-b ± √(b^2 - 4ac)) / 2a

where a, b, and c are the coefficients of the quadratic equation in the form ax^2 + bx + c = 0.

For the equation X^2 + 5x - 6 = 0, the coefficients are: a = 1 b = 5 c = -6

Now, we can plug these values into the quadratic formula:

X = (-(5) ± √((5)^2 - 4 * 1 * (-6))) / 2 * 1 X = (-5 ± √(25 + 24)) / 2 X = (-5 ± √49) / 2 X = (-5 ± 7) / 2

Now, we get two possible solutions for X:

1. X = (-5 + 7) / 2 X = 2 / 2 X = 1

2. X = (-5 - 7) / 2 X = -12 / 2 X = -6

So, the two solutions for the equation X^2 + 5x - 6 = 0 are X = 1 and X = -6.
