Question

One of the steps Misaki used to solve an equation is shown below.

Answer 1

Answer:

Distributive property

Step-by-step explanation:

The given equation is:

$2q(q+4)=10$

To solve this equation, we expand the left hand side using the distributive property to obtain:

$2q^2+8q=10$

That was exactly what Miskai did.

Therefore the property that justifies his step shown is the distributive property.

This property says that, if a, b, and c are real numbers then,

$a(b+c)=ab+bc$
