Is the quadratic formula the most efficient method for solving X 2 X 42 0?

Is the quadratic formula the most efficient method for solving X 2 X 42 0?

Yes, the quadratic formula is the most efficient method because it provides the fewest calculations.

What are the factors of x 2 12x 36?

That is, x2 -6x-6x+36.

Is x 2 4x 4 a perfect square?

Yes, x2 + 4x + 4, is a perfect square trinomial.

What is the factor of x 2 4?

1 Answer. x2+4 cannot be factored using real number coefficient. Depending on your class, that may be enough of an answer. If you really need to factor completely and are allowed to use complex numbers, you can.

Is x 2 20x 100 a perfect square trinomial?

As the provided trinomial is x^2 + 20x – 100, it is not a perfect square trinomial.

Is x 2 10x 100 a perfect square?

It is not a perfect square trinomial.

How do you make x 2 10x a perfect square?

The basic idea is to make a perfect binomial square show up by manipulating the original expression. The method is based on the simple observation that, while x2 + 10x is not a perfect square, x2 + 10x + 25 is. “Completing the square” means putting in the missing 25 that is needed to form the perfect square.

What could be added to each expression to make it a perfect square?

An expression is said to a perfect square trinomial if it takes the form ax2 + bx + c and satisfies the condition b2 = 4ac. The perfect square formula takes the following forms: (ax)2 + 2abx + b2 = (ax + b)

What number must be added to make a perfect square trinomial?

What square number must we add? We must add the square of half of coefficient of x. The trinomial will then be the square of (x + half-that-coefficient). We add the square of half the coefficient of x — half of 8 is 4 — because when we multiply (x + 4)2, the coefficient of x will be twice that number.

Is 8X2 a perfect square?

Answer: I think yes because the product of 8X2 is 16 and the square root of 16 is 4. Therefore, it is a perfect square.
