7 c 2 + 8 c + 1 = 0

Expert Solution & Answer
Check Mark
To determine

To solve : The quadratic equation using quadratic formula.

Answer to Problem 1P

The solution for the equation is c=17 and c=1 .

Explanation of Solution

Given information :

The given equation is 7c2+8c+1=0 .

Calculation :

For the quadratic equation ax2+bx+c=0 the quadratic formula is

  x=b±b24ac2a

Now, for the given equation 7c2+8c+1=0

  a=7 , b=8 and c=1 .

Therefore,

  c=8±824(7)(1)2(7)c=8±642814c=8±3614c=8±614c=8+614  and  c=8614c=214       and  c=1414c=17      and  c=1

Hence,

The solution for the equation is c=17 and c=1 .
