Roots: -4 and 3
Leading coefficient: 1
A polynomial equation is fully expanded when all like terms have been combined, end there are no variables inside parentheses.
Roots: (where the polynomial is equal to zero)
(x+4) (x-3)
The leading coefficient is the number that has the X raised to the highest exponent.
So, in expanded form:
(x+4) (x-3)
x^2-3x+4x-12
x^2+x-12
