Question

middle term splitting of x2-5x-180

Answer 1

Answer:

army please check the question

I think there should be 3x or 8x instead of 5x

x²-3x-180

x²-15x+12x-180

x(x-15) +12(x-15)

(x+12) (x-15)

x=-12,15

x²-8x-180

x²-18x+10x-180

x(x-18) +10(x-18)

(x+10)(x-18)

x=-10,18

HOPE IT HELPS YOU ARMY
