The LCM is the absolute value of x.
I assume you mean...,X2 + 11X + 10(X + 1)(X + 10)==============factored
x2 + 11x + 24 You want the equation to be in the form (x + a)(x + b), where the two solutions are -a and -b.You know that...ab = 24...and...a + b = 11Note that 8 times 3 is 24, and 8 plus 3 is 11.x2 + 11x + 24 = (x + 3)(x + 8)The two answers are x = -3 and x = -8.
It doesn't factor evenly if it were x**2-11x+10: x**2-11x+10 = (x-1)(x-10)
find factors of -3 (3 & -1 ) also add together to get 2 (for the 2x part) put x on both sides (x+3) (x-1) << because xsquared means x times x check it 3 times -1 = -3 3 times x = 3x -1 times x = -1x x times x = xsquared = xsquared + 2x -3 hope this helped =)
