## How do you factor Trinomial with two variables?

To factor a trinomial with two variables, the following steps are applied:
1. Multiply the leading coefficient by the last number.
2. Find the sum of two numbers that add to the middle number.
3. Split the middle term and group in twos by removing the GCF from each group.
4. Now, write in factored form.

## How do you factor a trinomial expression?

To factorise a trinomial expression, put it back into a pair of brackets. To find the terms that go in each bracket, look for a pair of numbers which multiply to give the last number and add together to give the middle number.

## What are some examples of quadratic equation in 2 variables?

A quadratic equation in two variables is an equation that’s equivalent to an equation of the form p(x, y)=0 where p(x, y) is a quadratic polynomial. Examples. 4×2 – 3xy – 2y2 + x – y + 6 = 0 is a quadratic equation, as are x2 – y2 = 0 and x2 + y2 = 0 and x2 – 1 = 0. y = x2 is a quadratic equation.

## How do you find the vertex of two variables?

We can easily find the coordinates of the vertex, because we know it is on the axis of symmetry. This means its x-coordinate is − b 2 a − b 2 a . To find the y-coordinate of the vertex, we substitute the value of the x-coordinate into the quadratic equation.
