Answer:
0
Step-by-step explanation:
Let's find f(3) first
All we need to do is plug 3 in the place of x
2(3) - 3
6 - 3 = 3
Now let's find f(0)
Do the same thing for the first one, plug the new number in the place of x
2(0) - 3 = -3
Not add both answers up
3 + -3 = 0
When we factorise an expression, we are looking for simple factors that multiply to get the original expression. Usually it is very natural to factorise something like a quadratic in x. For example:
x^2 + 3x + 2 = (x+1)(x+2)
But there are other situations where factorisation can be applied. Take this quadratic:
x^2 - 9x = x(x-9)
This second example is closer to the question in hand. Just like x was a common factor to both x^2 and -9x, we are looking for a common factor to both 6b and 24bc. The common factor is 6b.
Hence 6b + 24bc = 6b(1 + 4c).
I hope this helps you :)
