N = -1/3 is the answer to the problem
Hi,
Let's solve the equation step-by-step.
x2+10x−2=0
Step 1: Use quadratic formula with a=1, b=10, c=-2.
x=
−b±√b2−4ac / 2a
x= −(10)±√(10)2−4(1)(−2) / 2(1)
x= −10±√108 / 2
x=−5+3√3 or x=−5−3√3
Answer:
x=−5+3√3 or x=−5−3√3
Have a great day!
The sign of the greater number that u either multiplied or divided is ur new sign
1. Completing saquares permits to extract square root fo find the solutions.
This is the general equation when you complete the squares:
A(x-h)^2 + k = 0
Then you can obtain [x - h]^2 = - K/A and now you can extract square root in both sides.
2) If k and A have the same sigh, then - K/A is negative and the square root has not real solutions, i.e. the solution will be complex.
