Multiply all the terms in the first parenthesis to all the terms in the second parenthesis.
x * x = ? x * 4 = ? 3 * x = ? 3 * 4 = ?
Can you multiply those?
x 4x 3x and 12

The first one is incorrect, but the rest are right. \(\sf x \cdot x = x^2\)
So we have: \(\sf x^2 + 4x + 3x + 12\) Can you simplify that?
4x plus 3x is 7x
Yes, so our final answer is: \(\sf x^2 + 7x + 12\)
can you help me with more please?

Sure, that's what I'm here for.
Do the same thing we did last time.
m * m = ? m * -7 = ? 2 * m = ? 2 * -7 = ?
