16x - 8x + 12 = 78 + 22 or simplified to (16x-8x=8x)(78+22=100) 8x + 12 = 100 Simplify some more (Subtract 12 from both sides) 8x = 88 Divide both sides by 8, and x = 11
Perform the indicated subtraction. 12 - 9 = 3
18 + 7x - 12 + 5x = ?18 - 12+ 7x - 5x = ?6 + 2x = ?
-6to work it out: remember BIDMASso 3x2=6! then 6-12=-6
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 answer to 3x^2-16x-12
16x - 8x + 12 = 78 + 22 or simplified to (16x-8x=8x)(78+22=100) 8x + 12 = 100 Simplify some more (Subtract 12 from both sides) 8x = 88 Divide both sides by 8, and x = 11
16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11

x2-16x+48 = (x-4)(x-12) when factored
No. 7*3, alone, is bigger than 12.
(5x - 6)(x - 2)
5x2-16x+12 = (5x-6)(x-2) when factored with the help of the quadratic equation formula
5x2-16x+12 = (5x-6)(x-2) when factored
6x(3-3)x(2+12)
23 if you mean (12-3)x(2+5)
