Question

1 m² + m -20 pls help me out ​

Answer 1

Answer:

$m {}^{2} + m - 20 = 0 \\ = m {}^{2} + 5m - 4m - 20 = 0 \\ = m(m + 5) - 4(m + 5) = 0 \\ = (m + 5)(m - 4) = 0 \\ = m = - 5 \: \: and \: \: 4$

Hey! Mate Here is your solution. Thanks

Answer 2

correct question:- if m²+m-20=0 find m

Step-by-step explanation:

what to find if value of m?

solution:-

m²+m-20=0

m²+5m-4m-20=0

m( m+5)-4(m+5)=0

(m+5)(m-4)= 0

hence

m= -5 and m= 4
