Question

Find the missing coefficient. - y2 − [-5y − y(-7y − 9)] − [-y (15y + 4)] = 0

Answer 1

Answer:

its -8 if ur on plato be careful the negetive sign is already there <3

Step-by-step explanation:

have a good day

Answer 2

There is only one solution in the given equation -y2 − [-5y − y(-7y − 9)] − [-y (15y + 4)] = 0. In solving this problem, apply first PEMDAS (parenthesis, exponents,multiplication, division, addition, subtraction). Then equation will transform into -y2+5y-7y2-9y+15y2+4y=0. Combine terms with same power and achieve 7y2=0. Divide both sides with 7 and perform square root of zero. Since the root is zero, we have one solution of the given equation which is y=0.
