Question

solve 5Msquare-22m-15=0​

Answer 1

5m² - 22m -15 = 0

⟹ 5m² - 25m + 3m -15 =0

⟹ 5m(m -5) +3(m-5) =0

⟹ (5m +3)(m-5) = 0

⟹ (5m +3) = 0

⟹ m = -3/5

⟹ (m-5) = 0

⟹ m = 5

⟹ Roots/solutions are -3/5 & 5

Answer 2

5msqare-22m-15

=5msquare-25m+3m-15

=5m(m-5) + 3(m-5)

=(5m+3) and. (m-5)

therefore m= -3/5 and m=5
