y = 12x + 5x - 7 Since '12x' and '5x' both have the same variable, you are able to combine them. To do this you just need to add 12 + 5 to get 17. After doing this you can rewrite the equation as y = 17x - 7. You can then solve this equation for different values by plugging in a number for 'x' or 'y' or graphing the equation.
assuming you meant 5x2+12x+4 (5x+2)(x+2)
Just the one because if: 12x+6 = 5x then x = -6/7
a= 10, b= -7, c=-12 ac=10 x -12 ac=-120 120={1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60,120} 8 x - 15 10x + 8x- 15x -12x (10x + 8x) - (15x - 12x) 2(5x + 4x) - 3(5x + 4x) (2 - 3) ( 5x + 4x)
12x and then the squared. (the little two)
Think of this a 12 x-rays + 5 x-rays Makes 17 x-rays. 12x+5x=17x
5x-8 + 7x 12x-8 12x = 8 x = 8/12 x= 2/3
12x^3+17x^2+5x=0x(12x^2+17x+5)=0x(x+1)(12x+5)=0x=0x=-1x=-5/12
LCM(5x, 12x) = 60x
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
60
12x - 14 = 5x12x = 5x + 147x = 14x = 2
After collecting like terms, (3 - 5x - 5 - 12x) reduces to (-2 - 17x).
-12x-2Given: -5x-(7x+2)This is the same as -5x-1(7x+2). Use the distributive property and multiply the -1 through (7x+2).-5x-7x-2Simplify.-12x-2
5x7 - 2x9 + 5x or written properly, -2x9 + 5x7 + 5x
y = 12x + 5x - 7 Since '12x' and '5x' both have the same variable, you are able to combine them. To do this you just need to add 12 + 5 to get 17. After doing this you can rewrite the equation as y = 17x - 7. You can then solve this equation for different values by plugging in a number for 'x' or 'y' or graphing the equation.
