Solve for x in the equation x^2+2x+1=17

x= (-1+ √17) or (-1-√17)

Step-by-step explanation:

In this question, we have to solve for x from the given equation x² +2x+1 =17

Now, the equation can be rearranged to x² +2x -16 =0.

Here we can not apply the process of factorization to get the value of x.

Hence, we will use the Shridhar Acharya formula to solve the value of x.

{This formula gives, if ax² +bx +c =0 then, the value of x can be solved as

x=[-b±√(b²-4ac)]/2a }

Hence, in this case, the solution for x will be

x=

⇒ x=

⇒ x= (-1+ √17) or (-1-√17) (Answer)
