solve the engation using zero product property. i dont know how to do this
OpenStudy (asnaseer):
the zero product property says that if the product of two numbers is zero, then either one of them must be zero.
OpenStudy (anonymous):
yea but it = 0 so then one the numbers wouldnt be 0
OpenStudy (asnaseer):
so, in your example, we have:\[(x-2)(x+7)=0\]which implies that either:\[x-2=0\]or:\[x+7=0\]
OpenStudy (anonymous):
but i dont have 0 as an option of my choices? im confused

you need to solve the two equations above, i.e.:\[x-2=0\]and:\[x+7=0\]
OpenStudy (anonymous):
but i dont get how to solve it?
OpenStudy (asnaseer):
if\[x-2=0\]then what must x equal?
OpenStudy (anonymous):
2?
OpenStudy (asnaseer):
correct, now try the same with:\[x+7=0\]
