How many roots does y equals x2-2x plus 1?
normally an equation with the x value squared there would be two roots. the two roots are positive 1 and postitive 1. since they are they same number there is actually only one root.
What is the answer to negative 66 square roots of x plus 12 quantity squared?
Without an "equals" somewhere along the way, you only have an expression, not an equation.Without an equation, there is no question, and nothing to answer.
How many roots does y equals x2 - 2x plus 1 have It may help to graph the equation?
Factors are (x - 1)(x - 1) so only one root.
What are the roots of the quadratic equation 6x2-x15 equals 0?
In the absence of a proper statement of the equation I can only guess at answers. How about (2x + 3)(3x - 5) which is the factorisation of 6x2 - x - 15 = 0? In which case x = -2/3 or 5/3.
What does the discriminant tell us about the nature of the roots?
The equation ax^2 + bx + c = 0 where a, b and c are real and a is non-zero has discriminant D = b^2 – 4ac. Then,if D > 0 the equation has two real roots which are distinct;if D = 0 the equation has two real roots which are coincident;if D < 0 the equation has two roots which form a complex conjugate pair (advanced mathematics only).

When the roots are equal of a quadratic equation?
Write the quadratic equation in the form ax2 + bx + c = 0 The roots are equal if and only if b2 - 4ac = 0. The expression, b2-4ac is called the [quadratic] discriminant.
Why is an equation written in the form Ax plus By equals c called a linear equation?
The equation contains variables which are only raised to the first power.
How do you find the discriminant and number of real solutions to a quadratic equation?
The equation ax^2 + bx + c = 0 where a, b and c are real and a is non-zero has discriminant D = b^2 – 4ac. Then,if D > 0 the equation has two real roots which are distinct;if D = 0 the equation has two real roots which are coincident;if D < 0 the equation has two roots which form a complex conjugate pair (advanced mathematics only).
How can prove that x2 equals 0?
You can't prove it, because it's usually not true.The only time it's true is when x=0 .
Find the equation of x plus 3y equals 4?
This equation is unsolvable since there are two unknowns and only one equation. You would require a second equation in order to solve it.
Solve for x 3 - x 7?
-4
What is the answer to the discriminant equation of -4.9 plus 4.3t plus 10?
A discriminant is based on the differences between roots of an equation. A linear equation, such as the onle in the question, has only one root and therefore cannot have a discriminant.
