2 (5x-4) = ax +b
divide each side by ax
2(5x-4) = ax+b
10x-8 = ax+b (Both sides are in the same format so you can substitute in the values)
b = -8
It's simple. I need my x variable to have a positive coefficient, 10 is already positive; therefore, I simply conclude a = 10. B has to be negative, but in the equation is positive (+b) therefore I need a negative number to make b negative when multiplied (-*+)
c. b < 0
l (x - 3)^2 - 4 l = l x^2 -6x + 9 - 4l
l x^2 - 6x + 5 l = b
If b < 0, the equation cannot be factored, there will not be real solution.
Therefore, answer is c. b< 0
Hope this will helpful.
I THINK D)IS IS THE RIGHT ANSWER. B>0.I KNOW IT'S HELP YOU.
solve for b: 6=b
b can have any value less than zero so that the above is never true, in interval notation:
whose power in the senate is equal to the power of the speaker of the house?
