How can I solve a quadratic equations for x in terms of y?
A quadratic involving x and y is usually in the form 'y = ax2 + bx + c'. This form is y in terms of x, so we must rearrange it. y = ax2 + bx + c y/a = x2 + bx/a + c/a y/a = x2 + bx/a + d + e, where c/a = d + e, e = (b/a)2 y/a - e = x2 + bx/a + d y/a -e = (x + b/a)2 √(y/a - e) = x + b/a √(y/a - e) - b/a = x
How many real roots does the equation 2x2-5x-3 equals 0 have?
2x2 - 5x - 3 = 0 A quadratic equation expressed in the form ax2 + bx + c = 0 has two real and distinct roots when b2 - 4ac is positive. Using the figures from the supplied equation then b2 - 4ac = 52 - (4 x 2 x -3) = 25 + 24 = 49. Therefore there are TWO real and distinct roots.
Is y equals x2 plus 2 a linear equation?
No, y=x^2 + 2 is a quadratic equation. A linear equation is one in the form y=mx+b. A quadratic has a form y=ax^2+bx+c.
How do you solve for x in the equation x2-2x-2 equals 0?
To solve for x in the equation x2 - 2x - 2 = 0, use the quadratic equation, that is: For 0 = ax2 + bx + c, the roots (values of x) are defined as: x = [-b +/- sqrt(b2 - 4ac) ] / 2a (If that's hard to understand, google "quadratic formula"). It works out to x = 2.73, -0.73.
What does the a stand for in y equals ax2 plus bx plus c?
y = ax2 + bx + cThe graph is always a parabola.'a', 'b', and 'c' are numbers. Different values for 'a', 'b', and 'c' produce parabolas with different widths,noses at different heights and different left-right locations. They determine whether the parabolaopens up or opens down, and whether it crosses the 'x' and 'y' axes, and if so, where it crosses.
What is the general form of a quadratic equation?
ax2 + bx + c = 0
How do you write a quadratic equation in standard form?
ax2 + bx + c
What happens when A changes in the equation ax2 Bx c?
If you mean: ax2+bx+c = 0 which is the general form of a quadratic equation whereas a is > 0 and any increases to the value of a will effect the solutions of the equation.
What is the solution in standard form for ax2 plus bx plus c with only solution of 8?
ax2 + bx +c is an expression, not an equation. It cannot, therefore, have a solution. If the question concerns the equation ax2 + bx + c = 0 then the answer is ax2 - 16ax + 64a = 0 for any a other than 0.
A quadratic equation in standard form is written?
ax2 + bx + c = 0
Equation that can be expressed in the form of the equation y equals ax2 plus bx plus c?

What is the standard form of quadratic equation?
The standard form of a quadratic equation is ( ax^2 + bx + c = 0 ), where (a), (b), and (c) are constants and (a \neq 0).
What is standrd form of quadratic equation?
Ax2 + Bx + C = 0A, B, and C are constants (numbers)
How do you find the additive inverse of a quadratic equation?
Change all the signs. Suppose you have the quadratic equation: y = ax2 + bx + c Its additive inverse is -ax2 - bx - c.
