this week in math we started our polynomials unit. one main thing i learnt was distributive property, to do this you need to multiply the number outside of the brackets with the numbers inside of the brackets. and another thing i remember is that the shapes that are shaded in represent positive and the ones that aren’t shaded in represent negative.

2x (2x-1)

• 2×2=4×2
• 2×1=2x

4×2-2x
