  • Q5:
    2 pts
    For quadratic equation $-x^2=10$ choose the correct substitution for a, b and c in the standard form $ax^2+bx+c=0$.
    $a=-1 , b=0 , c=10$
    $a=1 , b=0 , c=-10$
    $a=-1 , b=0 , c=-10$
  • Q6:
    2 pts
    Solve $a^2+4a-5=0$ by using the quadratic formula.

    a = 1 , a = -5

    a = 1 , a = 5

    a = -1 , a = 4

    a = 1 , a = 4
