Question 1
(a) Solve the quadratic equation
x^2 + 4x -5 = 0
(b) Factorise its left hand side.
(c) Find interval(s) of x where the left hand side is positive
Q1
(a)
(x+-1) (x+5)
x= 1 x=-5
is that solving the equation?
(b)
didnt i already factorise the left hand side of the equation when i solved for in (a)?
(x+-1)?
(c)
not sure on this one
