Question

m²+m-72 factorise give the correct answer​

Answer 1

Answer:

m² + 9m - 8m - 72 = 0

m ( m +9 ) − 8 ( m + 9 ) = 0

( m + 9 ) ( m− 8 ) = 0 8 = 0

m + 9 = 0 or m = > m = -9 or m = 8

Answer 2

Answer:

m= -9,8

Step-by-step explanation:

Given that,

 m^2 + m - 72

= m^2 + 9m -8m - 72

= m(m+9) -8(m+9)

= (m+9) (m-8)
