$x\cdot x+4x+2x+2\cdot 4$

Learn how to solve special products problems step by step online. Solve the product (x+2)(x+4). We can multiply the polynomials \left(x+2\right)\left(x+4\right) by using the FOIL method. The acronym F O I L stands for multiplying the terms in each bracket in the following order: First by First (F\times F), Outer by Outer (O\times O), Inner by Inner (I\times I), Last by Last (L\times L):<ul><li>(F\times F) is (x)(x)</li><li>(O\times O) is (x)(4)</li><li>(I\times I) is (2)(x)</li><li>(L\times L) is (2)(4)</li></ul><p class='exp-text'>Then, combine the four terms in a sum: (F\times F) + (O\times O) + (I\times I) + (L\times L):</p>. Multiply 2 times 4. When multiplying two powers that have the same base (x), you can add the exponents. Combining like terms 4x and 2x.
