Answer
-3, 10
Work Step by Step
Since the coefficient of the squared term is one, we know that the expression must factor to:
$$ (x\pm a)(x\pm b)$$
Here, we see that a and b must multiply to get $-30$ and add to get $-7$. Thus, we find that the solution is:
$$(x-10)(x+3)$$
Thus, setting each factor equal to zero, we find that the zeros are:
$$ 10,-3$$
