(x+5)(x+6) equals x^2 +11x+30
2x + 7 + 5 = 2x + 12 = 2*x + 2*6 = 2*(x+6)
(x+2)/5 = 6+x x+2 = 30+5x x-5x = 30-2 -4x = 28 x = -7
-2(x + 5)(x - 6)
6x + 8 = 6 6x = -2 x = -2/6 x = -1/3
solving for the x variable given that x2-6x+5=0 factoring the polynomial gives (x-1)(x-5)=0 which leaves you with your two answers, x=1, 5 or you could have used the quadratic equation x = [ -(-6) plus/minus sqrt( (-6)2 - 4*1*5 ) ] / (2*1) x = [ 6 plus/minus sqrt( 36-20 ) ] / 2 x = [ 6 plus/minus 4 ] / 2 x = 3 plus/minus 2 x = 5, 1
2x2 - 5x + 6 = ?x = -1(2 x (-1)2) - (5 x -1) + 6 = ?(2 x 1) - (-5) + 6 = ?2 + 5 + 6 = 13
x + y = 6 so that -x = y - 6 -x + 3y = -2 that is, y - 6 + 3y = -2 or 4y = 4 or y = 1 and then -x = y - 6 = -5 so that x = 5
x (x+5) = 6 X equals 1.
3x+5<x+11 3x<6 x<2
18 + 6 + 2 = 26
