2x squared minus 5x minus 3 factored is (2x+1)(x-3).
Solve this problem -x squared -40x- 80 =0
(x - 5)(x + 4)
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.
The question contains an expression but not an equation. You cannot solve an expression.
Solve using the quadratic formula
You have to put your heart into it!
(x + 2)(x - 4)
Without an "equals" word or sign somewhere, there is nothing to solve.You only have an expression, not an equation.
x = ? 42 = x squared minus x
x(x + 3)(x - 4)
3x2 - 11x - 4 = (x-4)(3 x + 1)
x2 - 4= (x+2) (x-2)
x3 + 4x2 - 16x - 64 = (x + 4)(x + 4)(x - 4).
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.
