From the Quotient-Remainder Theorem follows that for every f(x) there exist unique polynomials q(x) and r(x) such that:
,
where r(x) is called remainder.
If r(x)=0, then f(x)=h(x)q(x) and q(x) is adivisor. If q(x) is of form q(x)=x-a, then a is a root of f(x).

Answer:
x = -15
y = -10
Step-by-step explanation:
To find the x intercept, we have to substitute 0 into y
4x + 6(0) + 60 = 0
4x + 0 + 60 = 0
4x + 60 = 0
4x = -60
x = -15
To find the y intercept, we have to subsitute 0 into x
4(0) + 6y + 60 = 0
6y + 60 = 0
6y = -60
y = -10
