Question

What steps can be used to solve the equation a +8 = - 5/a​

Answer 1

times by a on both sides

a(a+8)= -5

expand brackets

a^2 + 8a = -5

minus 5 on both sides to set equal to 0

a^2 + 8a -5 = 0

use quadratic formula to get 2 solutions

-

`\frac{ - (8) + or - \sqrt{ {8}^(2) - 4(1)(5) } }{2(1)}`
