Answer: −50x−66
Step-by-step explanation:
4(10x+6)−10(9x+9)
Distribute:
=(4)(10x)+(4)(6)+(−10)(9x)+(−10)(9)
=40x+24+−90x+−90
Combine Like Terms:
=40x+24+−90x+−90
=(40x+−90x)+(24+−90)
=−50x+−66
When b^2 -4ac >0 you get rational answers. I suppose you could use factoring as well as the quadratic formula.
when b^2 -4ac =0 You get one answer. Okay it is till technically "two" answers but you say BOTH values of x = whatever.
when b^2 -4ac <0 the answers are complex (imaginary) and have the value of "i" somewhere in them. For example the answers might be 2 + 2i that kind of thing
