Week 4 in Precalc 11

This week in math 11 we learned about adding and subtracting radicals and we also learned how to multiply and divide.

this week we were not solving equations we were simplifying them. so when we had the equation 3 \sqrt {2} + 2 \sqrt {2} – 5 \sqrt {2} then we would simplify that to \sqrt {2}

the way I solved it was by using like terms.

adding and subtracting radicals is quite simple. It’s just combining like terms. so if we have 5 \sqrt {3} – 2 \sqrt {3}, we would get 3 \sqrt {3}.
