Question

Simplify the following expression.

Answer 1

When simplifying the following expression we want to look first at adding like terms to together

2x² - 5x² = -3x²

Once the squared exponents are added together add the x’s together:

x + 7x + 7x = 15x

Now add the integers together:

1 + 5 + (-4) = 2

Since you can’t add exponents with each other unless the have the same exponent they stay the same:

The equation should look like this:

-3x² + 15x + 2 -3x²³

Now add the exponents together because it is exponents of x.

-6x^25 + 15x + 2

That is the most simplified version of the complex equation.
