Question

If (y - 1) is a factor of (my - 2y2 + y2 - 4), then find
the value of m.​

Answer 1

Answer: 5

Step-by-step explanation:

If (y -1) is a factor, then p(1)= 0 (remainder theorem)

p(y) = my - 2y² + y² - 4

p(1) = m(1) - 2(1²) + (1²) - 4

p(1) = m - 2 + 1  - 4

p(1) = m -5

We know p(1) = 0

∴ m - 5 =0

m = 5

Hope it helps you :)
