X2+3x+x+3=x(x+1)+3(x+1)=(x+3)(x+1)
-3(x - 3)(x + 1)(x + 1)
1 plus 1 x 2 plus 3 x 42 plus 10 x 5 = 1 + 2 + 126 + 50 = 179
x + x + 1 + x + 2 + x + 3 = -144x + 6 = 144x = 8x = 2
(2x + 3)(x + 1 ) = 2x^2 +5x +3
It is 123.99
X2+3x+x+3=x(x+1)+3(x+1)=(x+3)(x+1)
x2 + 4x + 3 =(x + 3) (x + 1)
-3(x - 3)(x + 1)(x + 1)
1 plus 1 x 2 plus 3 x 42 plus 10 x 5 = 1 + 2 + 126 + 50 = 179
x + x + 1 + x + 2 + x + 3 = -144x + 6 = 144x = 8x = 2
3(x+1) = 3x+3
(5x+3)(x+1) X = -3/5 or x= -1
(2x + 3)(x + 1 ) = 2x^2 +5x +3
2x + 3 = x + 1 Subtract x from both sides: x + 3 = 1 Subtract 3 from both sides: x = -2
3 x -3 + 1 = (-9) + 1 = -8.
5X-3 - X-1 + X + 6 The answerdepends on value of X
