Question

Solve. Express irrational solutions in simplest radical form. If the equations has no real-number solutions, write "no real-number solution."

1) (y-7)^2 = 0
2) a^2 = -9
3) 6t^2 = 156

Answer 1

1) \(y=7\)
2) No real solution
3) \(6t^2=156 \implies t^2=26 \implies t=\sqrt{26}\) ot \(t=-\sqrt{26}\).
