x2 + 3x + 3 = 7
Subtract 7 from each side:
x2 + 3x - 4 = 0
Factor the left side:
(x + 4) (x - 1) = 0
x = - 4
x = +1

X2 plus 3x-7 equals 5x plus 8?
x2 + 3x - 7 = 5x + 8; thus, x2 + 3x - 7 - 5x - 8 = x2 - 2x - 15 = (x - 5)(x + 3) = 0. Therefore the solution is x = 5 or -3.
Find the sum of the roots x2 plus 3x equals -2?
-3/2
What is the answer for x2 plus 3x-18 equals 0?
X2 + 3X - 18 = 0What two factors of - 18 add up to 3 ??(X - 3)(X + 6)============so, by the zero sum rule,X = 3X = - 6
What is x2 plus 3x plus x plus 3?
X2+3x+x+3=x(x+1)+3(x+1)=(x+3)(x+1)
If 3X - 1 equals 11 what is the value of X2 plus X?
3x-1 = 11 3x = 11+1 = 12 x = 12/3 = 4 Therefore: x2 + 2 = 16 + 2 = 18
How do you solve x2 plus 3x plus 3 0?
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
How do you solve this problem it just says solve x2 plus 3y equals 7 3x plus y2 equals 3?
x2 + 3y = 7 3x + y2 = 3 3y = x2 + 7 y2 = -3x + 3 y = x2/3 + 7/3 y = ± √(-3x + 3) If you draw the graphs of y = x2/3 + 7/3 and y = ± √(-3x + 3) in a graphing calculator, you will see that they don't intersect, so that the system of the given equations has not a solution.
X2 plus 3x-7 equals 5x plus 8?
x2 + 3x - 7 = 5x + 8; thus, x2 + 3x - 7 - 5x - 8 = x2 - 2x - 15 = (x - 5)(x + 3) = 0. Therefore the solution is x = 5 or -3.
Find the sum of the roots x2 plus 3x equals -2?
-3/2
How do you factor x3 plus x2-3x-3?
x3 + x2 - 3x - 3 x(x2 + x - 3) - 3
Factor by grouping 3-3x plus x2-x3?
3 - 3x + x2 - x3 = (1 - x)(x2 + 3)
One of the roots of the equation x2 plus 3x - 18 equals 0 is 3 what is the other root?
x2 + 3x - 18 = 0 (x - 3)(x + 6) = 0 x = 3 or -6
X2 plus 3x - 18 equals 0?
x^2+3x-18=0 (x+6)(x-3)=0
