1,2.5
Using the quadratic equation formula: x = -5-/+ the square root of 7
The quadratic equation in standard form is: ax2 + bx + c = 0. The solution is x = [-b ± √b2- 4ac)] ÷ 2a You can use either plus or minus - a quadratic equation may have two solutions.
The solution: x = 6/7 and x = -1
Without an equality sign the given expression can't be considered to be an equation but if it equals 0 then using the quadratic equation formula will give its solutions.
It will have two solutions because its a quadratic equation: x = -8.472135955 or x = 0.472135955
No. It is a quartic equation. The largest power of x in a quadratic equation must be 2.
-9
0x2 + 1x - 7 = 0
It is a quadratic equation and its solutions can be found by using the quadratic equation formula.
Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
To find the solution to this equation, you need to rearrange the terms and solve for the variable. 4 = 2b + b^2 can be rewritten as b^2 + 2b - 4 = 0. You can then solve this quadratic equation by factoring, completing the square, or using the quadratic formula.
A quadratic equation.
