No, the student is not correct. The factors of m²-15m + 50 cannot be (m + 5) (m + 10).
To check if the student's claim is correct, we can expand the expression (m + 5) (m + 10) using the distributive property:
(m + 5)(m + 10) = m(m) + m(10) + 5(m) + 5(10) = m² + 10m + 5m + 50 = m² + 15m + 50
As we can see, the expanded expression is m² + 15m + 50, which is different from the original expression m²-15m + 50 given by the student.
Thus, the student's claim is incorrect.
A student said the factors of
m²-15m + 50 are (m +5) (m + 10)
