Question

What is the product?

(x + 3)(2 x minus 1)

2 x squared minus 3
2 x squared + 6 x
2 x squared + 5 x minus 3
2 x squared + 6 x minus 3




What is the product?

(5r − 4)(r2 − 6r + 4)

5r3 − 34r2 + 44r − 16
5r3 − 4r2 + 14r − 16
5r3 − 6r − 16
5r3 + 10r − 16

Answer 1

1) (x + 3)(2x − 1) = 2x^2 + 5x − 3

2) (5r − 4)(r^2 − 6r + 4) = 5r^3 − 34r^2 + 44r − 16
