Answer:
d= im not sure/ sorry
a= three times a number equals nine
b= fifteen divided by a number equals three
c= a number minus six equals thirteen
d= twenty four times a number equals five hundred fifty-two

So it can be rewritten as this: -(x^2-3x-28)
Then we need to find two numbers that multiply to -28, but add up to -3.
Those two numbers are -7 and +4.

Answer:
are zeroes of given quadratic equation.
Step-by-step explanation:
We have been a quadratic equation:
We need to find the zeroes of quadratic equation
We have a formula to find zeroes of a quadratic equation:
General form of quadratic equation is 
On comparing general equation with b given equation we get
a=2,b=-10,c=-3
On substituting the values in formula we get
Now substituting D in 
we get
Therefore,
