2016年4月22日 · #y=|3 x + 6 |# is the combined equation for the pair of lines #y=+-(3 x + 6 )#, subject to the condition #y >= 0#. These two lines cut at #(-2, 0)# The V-like part of the pair of lines from and above the point of intersection #(-2, 0)# makes the graph.

2017年3月29日 · The equation becomes this: #(x^3-2x^2)-(2x^2-x-6)#. We can factorize each of the expressions in the parentheses: #x^2(x-2)-(x-2)(2x+3)#. There is a common factor #(x-2)#. Factoring the common factor out, we get #(x-2)(x^2-2x-3)#. We then factorize #x^2-2x-3# to #(x-3)(x+1)#. The fully factored form is then #(x-2)(x-3)(x+1)#.

2015年12月30日 · Substitute the coefficients a=1, b=3 and c=6 into the quadratic formula to find: x=(-3+-i sqrt(15))/2 x^2+3x+6 is in the form ax^2+bx+c with a=1, b=3 and c=6. First note that the discriminant Delta is negative. Delta = b^2-4ac = 3^2-(4xx1xx6) = 9 - 24 = -15 So our quadratic equation has two Complex roots. The roots are given by the quadratic formula: x = (-b+ …

2016年2月29日 · x=5 3x + 6 = 21 Following the correct rules in math: Subtract both sides with "-6" to isolate 3x, making the equation looks like this: 3x + 6 - 6 = 21 - 6 3x = 15 Divide both sides by 3 to come up with x, making the equation: cancel((3x)/3) = cancel(21/3) Final answer is: x=5 SHORTCUT METHOD: This one does not follow the correct rules in math but this is very …

2017年8月21日 · See a solution process below: First, solve the equation for two points and plot the points on the graph: For y = 3: 3 + 3 = x + 6 6 = x + 6 6 - color(red)(6) = x + 6 - color(red)(6) 0 = x + 0 0 = x x = 0 or (0, 3) For x = 3: y + 3 = 3 + 6 y + 3 = 9 y + 3 - color(red)(3) = 9 - color(red)(3) y + 0 = 6 y = 6 or (3, 6) graph{(x^2+(y-3)^2-0.05)((x-3)^2+(y-6)^2-0.05)=0 [-15, 15, -7.5, 7.5]} …
