(x)(x + 13) = 0
x = 0 and x+13 = 0
x = 0 and x = -13
{-13,0}

If you use this property, you can just make each of the two terms equal zero and solve.
x=0 That's easy, one answer is 0.
x+13=0
x=-13 The other answer is -13.
{-13, 0}

Hello,
If two quantities = 0 then one or both must be = 0.
So x = 0 or x+13 = 0 then x = 0 or x = -13. Hence (-13,0)
Hope This Helps!!

x= 0
x+13 = 0 which mean x=-13
-13,0

3x^2 + 14x + 8 = 0 Quadratic formula gives x to be -4 or -2/3 Alternatively, factorise to (3x+2)(x+4) Giving x as -2/3 or -4
