Worksheet 2 6 Factorizing Algebraic Expressions

This equation should be veri ed by expanding the right hand side Example 1 : Factorize x2 +9x+14 We attempt to nd two numbers that add to give 9 and multiply to give 14, and the numbers that do this are 2 and 7 Therefore x2 +9x+14 = (x+2)(x+7) Again, this equation shouldn’t be believed until the right hand side is expanded,

Differential Equations I

A diﬀerential equation (de) is an equation involving a function and its deriva-tives Diﬀerential equations are called partial diﬀerential equations (pde) or or-dinary diﬀerential equations (ode) according to whether or not they contain partial derivatives The order of a diﬀerential equation is the highest order derivative occurring
