to solve this equation
we first identify it as quadratic and to solve we find two numbers that can multiply to get -40 and add to get positive three
the factors being-5 and positive 8 satisfied the condition now to apply zero product principle
from the equation above in (x-5)=0 we subtract 0 from both places and it literally reads
for the second the same is done
now for second question
not forgetting the zero. open two brackets and find no that can add to get 3 and multiply to get 1
the answer being x=-1 and x=-1
