Question

solve the following quadratic equation by using formula 5m²=4m+9​

Answer 1

Answer:

5m^2-4m-9

5m^2-9m+5m-9

m(5m-9)+1(5m-9)

(m+1)=0&(5m-9)=0

m=-1&m=9/5

Answer 2

Step-by-step explanation:

$= {ax}^{2} + bx + c = 0 \\ = {5m}^{2} - 4m - 9 = 0 \\ = 5 { m}^{2} -m (9 - 5) = 0 \\ = 5 {m}^{2} - 9m + 5m - 9 = 0 \\ = m(5m - 9) + 1(5m - 9) \\ = (m + 1)(5m - 9)$

So in the above first we change into a standard form of quadratic equation ..

than we solve it ..I hope it will help you
