15 = 8x2 - 14x; whence,
8x2 - 14x - 15 = (2x - 5)(4x + 3) = 0.
Therefore, x = 5/2 or -3/4.

It depends on which variable you wish to solve for.
You cannot solve one linear equation in two unknown variables.
A parabola is a graph of a 2nd degree polynomial function. Two graph a parabola, you must factor the polynomial equation and solve for the roots and the vertex. If factoring doesn't work, use the quadratic equation.
(3x+4)(3x-4)=0 x=±4/3
y=b+x+x^2 This is a quadratic equation. The graph is a parabola. The quadratic equation formula or factoring can be used to solve this.
Solve by factoring. Solve by taking the square root of both sides.
It means you are required to "solve" a quadratic equation by factorising the quadratic equation into two binomial expressions. Solving means to find the value(s) of the variable for which the expression equals zero.
It is not an equation if it does not have an equals sign. You could simplify it but not solve it.
The discriminant for the quadratic is b2-4ac = 302 - 4*4*45 = 900 - 720 = 180 Since 180 is not a perfect square, the roots of the equation are irrational and it is far from straightforward to solve such an equation by factoring.

Four? Factoring Graphing Quadratic Equation Completing the Square There may be more, but there's at least four.
To solve a quadratic equation using factoring, follow these steps: Write the equation in the form ax2 bx c 0. Factor the quadratic expression on the left side of the equation. Set each factor equal to zero and solve for x. Check the solutions by substituting them back into the original equation. The solutions are the values of x that make the equation true.
You cannot solve it since it is not a true equation.
Divide each side of the equation by 10 .
