Which equation has the same solution as x2 + 12x - 15 = 0?

x = 1.14 or x = - 13.14

Step-by-step explanation:

X² + 12x - 15 = 0

Using quadratic equation formula,

x = [-b ± √ (b² - 4ac) ] / 2a

a = 1, b = 12, c = - 15

Substituting the respective values into the equation,

x = [-12 ± √ (12² - (4*1*-15) ] / 2 * 1

x = [-12 ± √ (204) ] / 2

x = (-12 ± 14.28) / 2

x = (-12 + 14.28) / 2 or x = (-12 - 14.28) / 2

x = 1.14 or x = - 13.14
