x2 - 12x + 35
Using the quadratic equation formula: x = -5-/+ the square root of 7
x^2-3x-28=0...................
How about finding the solutions of the quadratic equation: x^2-14x+49 = 0
52-4*7*1 = -3 The discriminant is less than zero so the quadratic equation will have no solutions.
4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
It is a quadratic equation that has 2 solutions
2x2-10+7 = 0 Solving the quadratic equation using the quadratic formula will give you two solutions and they are: x = (5 - the square root of 11)/2 or x = (5 + the square root of 11)/2
There are two solutions for x: x=11 and x=-7
Using the quadratic equation formula: x = -5-/+ the square root of 7
-3
9x2+6x-7 = 0 Using the quadratic equation formula:- x = 0.6094757082 or x = -1.276142375
x^2-3x-28=0...................
To solve the quadratic equation, S^2 + 4S - 21 = 0, you can factor the expression or use the quadratic formula. Factoring, we can rewrite it as (S-3)(S+7) = 0. This means that either S-3 = 0 or S+7 = 0. Solving for S in each case gives S = 3 or S = -7 as the solutions to the equation.
