It is x^2 -13x +12 = (x-1)(x-12) when factored
It is: (x+1)(x+12) when factored
2x+x+x+9x+2+12 - add the like terms =13x+14 13x and 14 cannot be added because they aren't like terms.
13x = -156 so x = -12
x + 13x + 10x = 50 - 6
x2 + 13x + 12 = (x + 1)(x + 12)
It's a quadratic expression: x²+13x+12 If, for example, x²+13x+12 = 0 then there are 2 roots, x=-1 and x=-12
It is x^2 -13x +12 = (x-1)(x-12) when factored
It is: (x+1)(x+12) when factored
2x+x+x+9x+2+12 - add the like terms =13x+14 13x and 14 cannot be added because they aren't like terms.
(4x2 - 13x - 12)/(4x+ 3) = (4x + 3)(x - 4)/(4x + 3) = (4x + 3)(x - 4)/(4x + 3) = x - 4 :)
13x = -156 so x = -12
x + 13x + 10x = 50 - 6
4x2+13x+3 m*n=(4*3)=12 m+n=13 m=12 n=1 (4x/12)=(x/3) (4x+1)(x+3)
X = 12
x2 + 13x + 36 = (x + 9)(x + 4)
-7+x=13x the -7=12x and x =-7/12
