# How do you multiply algebraic expression such as related homework questions

• #### I want to know did I work these problems right Multiply: ( - 6)² - 4² = 36 – 16 = 20 Multiply ( - 3) ( - 6 ) + ( 4 ) ( -2) = 18 + ( -8) = 18-8= 10 Multiply: ( - 3 ) ³ - ( - 8) ( -2) = (-3) times 3 = -9 (-8) times (-2) = 16 -9 - 16 = -25 -25 Multiply

• #### Can someone show me how do i multiply the following fractions: (n^2-n-20)/(2n^2) times (n^2+5n)/(n^2-25) When you multiply fractions, you just multiply straight across

Can someone show me how do i multiply the following fractions: (n^2-n-20)/(2n^2) times (n^2+5n)/(n^2-25) When you multiply fractions, you just multiply straight across. So if you have: 1/3 * 1/4 1*1 ---- 3*4 That's 1/12 With that in mind, let's look at your question: (n^2-n-20)(n...
