SAT Math (Thanks and please help!) r(x) = 2(x^2-11x+3)+7(x+m)In the polynomial defined above, m is a constant. If r(x) is divisible by x, what is m?
Accepted Solution
A:
Answer: m = -6/7Step-by-step explanation:The constant term in the sum is ... 2·3 +7·m = 6+7mIn order for r(x) to be divisible by x, this value must be zero: 6 + 7m = 0 6/7 + m = 0 . . . . . divide by 7 m = -6/7 . . . . . . . . subtract 6/7
