How do you simplify -3x2 plus 16x plus 12?
-3x2 + 16x + 12 = -3x2 + 18x - 2x + 12 = -3x*(x - 6) - 2(x - 6) = -(3x + 2)*(x - 6)
What is the discriminant of the equation -3x square - 12x plus 7 equals 8?
The equation is equivalent to: -3x2 - 12x - 1 = 0 [you could change signs to get 3x2 + 12x + 1 = 0 but that is not required] The discriminant is (-12)2 - 4*(-3)(-1) = 144 - 12 = 132
What is the complete factorization of 10x - 3 - 3x2?
-3x2+10x-3 -(3x2-10x+3) -(3x-1)(x-3)
What operation should be done first 6 3x2?
3x2 if it is in parentheses
What can you multiply to get 96?
96= 48x2 48= 24x2 24= 12x2 12= 6x2 6= 3x2 Thus 96= 2x2x2x2x3
How do you simplify -3x2 plus 16x plus 12?
-3x2 + 16x + 12 = -3x2 + 18x - 2x + 12 = -3x*(x - 6) - 2(x - 6) = -(3x + 2)*(x - 6)
What is the answer to 3x2-16x-12?
what is the answer to 3x^2-16x-12
What is the result of 12-3x2 plus 15?
153
Factor completely 3x2 7x-12?
3(0)^2+7(x)-12 = -12
3x2 plus 12x equals -1?
3x2 + 12x = - 1 ie 3x2 + 12x + 1 = 0 has no rational roots. The irrational roots are [-12 +/- sqrt(132)]/6 = -3.915 and -0.085
What does 2x6 times 3x2 equal?
It is equal to to 72 because 2x6=12 and 3x2=6 and 12x6=72 or if you think this is to complicated, you can do 2x6=12, 12x3=36, and then 36x2, which then also gives you 72
What are the possible zeros of 6x3-3x2 plus 12?
6x(3-3)x(2+12)
What is the value of 12-3x2 plus 5?
23 if you mean (12-3)x(2+5)
What does 6 equal to?
12
2x1 plus 3x2 plus 7x3 equals 12?
