How many solutions are there to the equation x3 - 7 0?
None because without an equality sign the given expression is not an equation and so therefore no solutions are possible.
How many solutions are there in the quadratic equation x2 - 4x - 77 equals 0?
There are two solutions for x: x=11 and x=-7
What are the solutions to this equation 9x2 plus 6x-7 equals 0?
9x2+6x-7 = 0 Using the quadratic equation formula:- x = 0.6094757082 or x = -1.276142375
How do I work out 5xsquared plus 12x plus 7 equals 0?
5x2 + 12x + 7 = 0 This equation can be factored : (5x + 7) (x + 1) = 0 The equation equals zero when either 5x + 7 = 0 or x + 1 = 0 When 5x + 7 = 0 then 5x = -7 : x = -7/5 or -1.4 When x + 1 = 0 then x = -1 The solutions or roots of this equation are x = -7/5 and x = -1
How many solutions are there to the equation x2-7 equals 0?
There are 2 answers, +sqrt 7 and -sqrt7. Generally, the highest exponent in the expression (in this case 2) is the maximum number of possible answers.
