x + a) (x + b) = x2 + (a + b) x + ab.

## What is the formula of XA XB?

The product of them is equal to an algebraic expression x 2 − ( a + b ) x + a b . Therefore, the product of special binomials and is expanded as x 2 − ( a + b ) x + a b in algebraic mathematics.

## What is the formula of XA )( XB?

Answer. (x-a)(x-b) is equal to x^2-xb-ax-ab= x^2 -x(b+a) –ab or = x^2 -b(x+a) –ax. The x minus a and b takes the quadratic formula and includes steps that should govern with above formula by operating and come across in an identify of same sort.

## How many terms are there in the expression 5xy2?

There are 4 terms.

## In which of the following the two expressions are like terms?

Answer: 7x and 4x is the two expressions which are like terms.

## Is 7x and 7y like terms?

NO,Terms whose variables (such as x or y) with any exponents (such as the 2 in x2) are the same. But 7x and 7×2 are NOT like terms (the exponents are different), they are unlike terms. Like terms can be added together.

## How do you divide unlike terms?

What Are Like and Unlike Terms?

1. Divide coefficients together.
2. List all the variables that occur in the terms being divided.
3. Subtract the exponents of like variables.

## How do you divide quadratic expressions?

Here are the steps in dividing polynomials using the long method:

1. Arrange the indices of the polynomial in descending order.
2. Divide the first term of the dividend (the polynomial to be divided) by the first term of the divisor.
3. Multiply the divisor by the first term of the quotient.

## How do you divide one polynomial by another?

Divide the term with the highest power inside the division symbol by the term with the highest power outside the division symbol. Step 3: Multiply (or distribute) the answer obtained in the previous step by the polynomial in front of the division symbol.
