It is known that M is an integer. If the quadratic trinomial x square + MX + 16 can be decomposed by cross multiplication, try to find all the m values that meet the conditions and decompose the factors

It is known that M is an integer. If the quadratic trinomial x square + MX + 16 can be decomposed by cross multiplication, try to find all the m values that meet the conditions and decompose the factors

16=1*16=2*8=4*4
be
1) M = 1 + 16 = 17 original formula = (x + 1) (x + 16)
2) M = - 1-16 = - 17 original formula = (x-1) (x-16)
3) M = 2 + 8 = 10 original formula = (x + 2) (x + 8)
4) M = - 2-8 = - 10 original formula = (X-2) (X-8)
5) M = - 4-4 = - 8 original formula = (x-4) ^ 2
6) M = 4 + 4 = 8 original formula = (x + 4) ^ 2
