The answer is one because according to pemdas you must do the parentheses first then do the rest
In quadratic equations,
a + b = -B
ab = C
where a and b are the roots, B is the second term, and C is the constant.

a + b = -12
ab = 35
The values of a and b from the equation is -7 and -5. Thus, the lesser root is -7.
