12x^3+17x^2+5x=0x(12x^2+17x+5)=0x(x+1)(12x+5)=0x=0x=-1x=-5/12
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
First, get everything that is like together. The -5 and the 3 are like and together they make -2. The -12x and the -5x and like and together they make -17x. The final answer is -17x-2
3x-8+5x+39+4x+51 = x(3+5+4) + -8 + 39 + 51 = 12x +82

Think of this a 12 x-rays + 5 x-rays Makes 17 x-rays. 12x+5x=17x
Work it out. 5x+3y=3 3y=-5x+3 y=-5/3x+1 -5/3=the slope in this equation -12x+20y=0 20y=12x y=12/20x y=3/5x 3/5=the slope in this equation If the slopes equal each other, the lines are parallel. If they are the negative reciprocal (the fraction flipped upside down and multiplied by -1) of each other, they are perpendicular. I can't believe I just helped someone this lazy.
This uses the distributive property.
5x-8 + 7x 12x-8 12x = 8 x = 8/12 x= 2/3
LCM(5x, 12x) = 60x
(3x - 2)(5x + 6)
3x-8+5x+39+4x+51 = x(3+5+4) + -8 + 39 + 51 = 12x +82

12x - 14 = 5x12x = 5x + 147x = 14x = 2
