What is (x + 3)(x + 4)?
Answer
x2 + 7x + 12
What is (x – 2)(-3x + 10)?
-3x2 + 16x – 20
What is (4x + xy)(-y + xy)?
-4xy + 4x2y – xy2 + x2y2
Multiply (-2x + 4)(3x2 + 9).
-6x3 + 12x2 – 18x + 36
Multiply (-4x3 – 7x)(10x – 1).
-40x4 + 4x3 – 70x2 + 7x
Multiply (10x + 7)(x3 – 6).
10x4 + 7x3 – 60x – 42
Multiply (2xy + x)(y + y2).
3xy2 + 2xy3 + xy
Multiply (5x2 + x)(y – 3y3).
5x2y – 15x2y3 + xy – 3xy3
