x2+7x+12=0
usually this means to factor the equation.
factored this equation would be...
(x+3)(x+4)
7x = 3x - 12 4x=-12 x=-3
x2+7x+12=0 x2+7x=-12 x+Sqaure Root of 7x= 2(SQ Root Symbol)3
x=12
7x + 16 = 3x + 4 4x = -12 x = -3
The math equation of X times 2 - 7x + 12 times 0 equals 2X - 7x.
3x + 4x = 847x = 84divide both sides by 7x = 12
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
simplify it, 7x-12=x+2+2x-3x 7x=2+12+3x-3x 7x=14 x=2
(4, -2)
28=8x+12-7x 28=8x-7x+12 28=x+12 28-12=x+12-12 16=x
many solutions
7x = -3y + 12
