The diagram shows OA = a and OB = b b) The point B divides AC in the ratio 2:3.
Work out vector OC in terms of a and b.​

Solve 2x+y=3 x+y=5 in substitution method

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares

For each polynomial, determine the degree and write the polynomial in descending order. a. –4x^2 – 12 + 11x^4 b. 2x^5 + 14 – 3x^4 + 7x + 3x^3
