Question

solve: 5m^2-22m-15=0

Answer 1

Hello!!!

Here's the Answer :


$5 {m}^{2}$ - 22m - 15 = 0

$5 {m}^{2}$ + 3m - 25m - 15 = 0

m (5m + 3) -5 (5m + 3) = 0

(5m + 3)(m - 5) = 0

=>(5m + 3) = 0
5m = -3
m = -3 /5

=> (m - 5) = 0
m = 5


Hope It Helps!!!

Answer 2

5m²-22m-15=0
5m²-25m+3m-15=0
5m(m-5) +3(m-5)=0
(5m+3)(m-5)=0
so, 5m+3 =0
m =-3/5
m-5= 0
m=5
