:Pulling out like terms

:Pulling out like terms 3.1 Pull out like factors :

:Pulling out like terms 3.1 Pull out like factors : -x2 + 150x - 5000 = -1 • (x2 - 150x + 5000)

:Pulling out like terms 3.1 Pull out like factors : -x2 + 150x - 5000 = -1 • (x2 - 150x + 5000) Trying to factor by splitting the middle term

:Pulling out like terms 3.1 Pull out like factors : -x2 + 150x - 5000 = -1 • (x2 - 150x + 5000) Trying to factor by splitting the middle term 3.2 Factoring x2 - 150x + 5000

:Pulling out like terms 3.1 Pull out like factors : -x2 + 150x - 5000 = -1 • (x2 - 150x + 5000) Trying to factor by splitting the middle term 3.2 Factoring x2 - 150x + 5000 The first term is, x2 its coefficient is 1 .
