Jillian is trying to factor this quadratic equation x^2+7x=−10. What property of equality must she use to set her equation equal to 0, so that she can factor correctly?(1 point)

Answer 1

To set the quadratic equation \( x^2 + 7x = -10 \) equal to 0, Jillian can use the Addition Property of Equality. This property states that if you add (or subtract) the same value from both sides of an equation, the two sides remain equal.

In this case, Jillian can add 10 to both sides of the equation:

\[ x^2 + 7x + 10 = 0 \]

Now, she can factor the quadratic equation correctly.
