There are several ways to solve x2-x-12. The easiest way, if you have a graphing calculator, is to put y = x2-x-12 and y = 0 into the graph and then solve for the intercepts. A way to do it without a graphing calculator is by factoring. x2-x-12 factors into (x-4) and (x+3). Then set (x-4) and (x+3) each equal to zero and solve. (x-4)=0 becomes x=4. (x+3)=0 becomes -3. Therefore, the answers are -3 and 4.
Solve this problem -x squared -40x- 80 =0
3x2 when x = 2 is the answer 3 X 4 = 12 or is the answer (3 X 2)2 = 62 = 36
(x - 12)(x + 12)
(x - 5)(x + 12)
By factoring I get x-3 divided by x+3
The answer to x2 - 2x - 4y2 - 4y =(x - 2y)(x - 2y - 2)
whp do you do a 7 suared
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
Solve this problem -x squared -40x- 80 =0
3x2 when x = 2 is the answer 3 X 4 = 12 or is the answer (3 X 2)2 = 62 = 36
If x squared -10 = 0 then x = the square root of 10
The question contains an expression, not an equation or inequality. There is nothing to solve in an expression.
It is x^2 -x -12 is (x+3)(x-4) when factored
Solve using the quadratic formula
Expression: x^2 -x -12 Completing the square: (x -0.5)^2 -12.25
The question contains an expression but not an equation. You cannot solve an expression.
