This week we continued multiplying polynomials. We were shown simple binomials and shortcuts we could take. Take an equation such as (x+2)(x+5) first of all we know x multiplied by x is x2 ( x squared) next we can add 5+2 to get 7, so far we have, x2+7. Next we can multiply 5×2 for 10 which finishes the equation. Therefore we get x2+7+10.
