3x - 2y + 7x + 4y = 3x + 7x - 2y +4y = (3+7)x + (-2+4)y = 10x + 2y
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
6x2 = -7x -2 6x2 + 7x + 2 = 0 6x2 + 3x + 4x + 2 = 0 3x(2x + 1) + 2(2x + 1) = 0 (2x + 1)(3x + 2) = 0 2x + 1 = 0 or 3x + 2 = 0 So, x = -1/2 or -2/3
7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3
(x2 + 7x - 18) = (x + 9)(x - 2)
It is a quadratic expression and can be factored into: (3x+1)(x+2)
The 3x is cubed and the 4x is squared
simplify it, 7x-12=x+2+2x-3x 7x=2+12+3x-3x 7x=14 x=2
3x + (-2 + 4x) = -2 + 7x
7x+2 = 3x-2 7x-3x = -2-2 4x = -4 x = -1
(3x+2)-(5+7x) = 3x+2-5-7x = -4x-3 3x+2 is -4x-3 times greater than 5+7x.
You're asking for the difference: (3x + 2) - (5 - 7x).(3x + 2) - (5 - 7x) =3x + 2 - 5 + 7x =10x - 3.It is (10x - 3) greater.
7(3y-2)-(-4y+9)
2x2 + 7x + 6 = 2x2 + 4x + 3x + 6 = 2x(x + 2) + 3(x + 2) = (x + 2)(2x + 3)
3x - 2y + 7x + 4y = 3x + 7x - 2y +4y = (3+7)x + (-2+4)y = 10x + 2y
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
7x + 5 + 3x is [ 10x + 5 ].That's the same thing as [ 2 times (5x + 1) ] .
