## What are the factors of 3x?

Factor pairs of (c -28) -x26gt; (-2, 14)(-4, 7). This sum is 3 -b. Then the 2 real roots are: **-4 and 7**

## What are the factors of 2x 2 5x 3?

The first term, the 3x, can be factored **as (3)(x); the second term, the 12, can be factored as (3)(4). The only factor common to the two terms (that is, the only thing that can be divided out of each of the terms and then moved up in front of a set of parentheses) is the 3.**

## What is the factor of x2 3x 54?

(**x−6)(x+9**) are the factors of the quadratic

## Which binomial is a factor of x2 3x 28?

## What are the roots of quadratic equation x2 3x 1 0?

If x^2 + 3x + 1 0 , then the roots of the equation are **x -3 xb1 u221a(m)/2 .**

## What is the solution of x2 3x 0?

x=0or**x=3** is the correct Solution

## What is the solution of x2 3x 40 0?

The answers for x2+3x−40=0 are **-8 and 5**

## Which number is added to perfect square x2 16x?

We have to add **82 64, to convert it into a perfect square. Therefore, 64 must be added to the expression to make it a perfect-square trinomial.**

## Can you factor x2 16?

There are **two ways to factorize x2u221216 – one using identity a2u2212b2(a+b)(au2212b) . Other method is by splitting the middle term, which is 0 here and as product of coefficient of x2 and constant term is u221216 . we need to do is to split middle term in 4 and u22124 (as their sum is zero and product is u221216 ).**

## What is x2 9 Factorised?

To complete the square, you take the square root of the number in the question. Remember that there will be a positive and a negative square root, so here the roots of 9 will be 3 and -3. Then you can factorise the expression like so:**x2-9(x+3)(x-3)Notice how each bracket contains an x and one of the square roots?**

## Which is the perfect square trinomial?

A perfect square trinomial is **a trinomial that can be written as the square of a binomial. Recall that when a binomial is squared, the result is the square of the first term added to twice the product of the two terms and the square of the last term. We can use this equation to factor any perfect square trinomial.**

## How many real answers does the quadratic equation x2 − 16x 64 0 have and what are the solutions?

3.3 Solving x2-16x+64 0 by the Quadratic Formula . This quadratic equation has **one solution only. That’s because adding zero is the same as subtracting zero.**
