Answer:
{-5-2*x^2-(-15)=0}
Step-by-step explanation:
That's the answer i believe??
Subtract 3 to get:
7k^2-6k=0
Clearly, we can factor out a k to find that:
k(7k-6)=0
If either k or 7k-6 is zero, the whole expression is zero, so our solutions are zero and 6/7.

Answer:
x^2-5x + 6
Step-by-step explanation:
Here, we want to expand the given expressions
To do this, we multiply each term in the first bracket with each term in the second
We then proceed to collect like terms
We have this as;
x(x-3) - 2(x-3)
= x^2 - 3x -2x + 6
= x^2 -5x + 6
