All I can see is the equation. What is it asking?
Factoring f(x) would give a factor (x-1-2i), so you can divide f(x) by this, leaving (x-3)(x+4)(x-1+2i), so the other roots are:
x=3
x=-4
x=1-2i
The answer to this question is c I think
Step-by-step explanation:
what do we need to do ?
just calculate the value of the expression by using the given values for the variables ?
what's the problem ? this is just basic calculation.
8/4 + 7×9 = 2 + 63 = 65
remember (please, for your life !) that multiplication and division always happens before any addition or subtraction (except for the case, where brackets force us in a different direction).
Answer :
5(x-6)(x-2)
= 5 [ x^2 -2x -6x +12 ]
= 5 (x^2 -8x +12)
= 5x^2 -40x +60
