Question

the zeroes of polynomial x^2-3x-m(m+3) are​

Answer 1

Answer:

f(x) = x2 – 3x – m (m + 3) By adding and subtracting mx, we get f(x) = x2 – mx – 3x + mx – m (m + 3) = x[x – (m + 3)] + m[x – (m + 3)] = [x – (m + 3)] (x + m) f(x) = 0 ⇒ [x – (m + 3)] (x + m) = 0 ⇒ [x – (m + 3)] = 0 or (x + m) = 0 ⇒ x = m + 3 or x = –m So, the zeroes of f(x) are –m and +3.Read more on Sarthaks.com - https://www.sarthaks.com/129532/find-the-zeroes-of-the-polynomial-x-2-3x-m-m-3
