Answer:
Two solutions were found :
x =(6-√40)/2=3-√ 10 = -0.162
x =(6+√40)/2=3+√ 10 = 6.162
Step-by-step explanation:
Trying to factor by splitting the middle term
1.1 Factoring x2-6x-1
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 1 • -1 = -1
Step-2 : Find two factors of -1 whose sum equals the coefficient of the middle term, which is -6 .
-1 + 1 = 0
