Move the constant term to the right side of the equation. 2. Multiply each term in the equation by four times the coefficient of the x squared term. 3. Square the coefficient of the original x term and add it to both sides of the equation. 4. Take the square root of both sides. 5. Set the left side of the equation equal to the positive square root of the number on the right side and solve for x. 6. Set the left side of the equation equal to the negative root of the number on the right side

A boat floats‚ because the fluid in which it is floating offsets the downward pull of gravity and pushes it up. The scientific name for this force‚ which allows even immense objects to float in liquid‚ is buoyant force‚ more commonly known as buoyancy. A solid object’s density determines whether or not the buoyant force of a liquid can lift it. The density of an object depends upon its weight and its size. Given two solid objects that are different sizes‚ but weigh the same‚ the smaller‚ more

Dq 2 week 1 I would explain that when multiplying polynomial is when all the variables have integer exponents that are positive. This works with addition‚ subtraction and multiplication. It has to be possible to write the equation without division for it to be a polynomial. This is an example of what a polynomial looks like: 4xy2+3X-5. To multiply two polynomials‚ you must multiply each term in one polynomial by each term in the other polynomial‚ and then add the two answers together. After
