There are many other types of equations in addition to the ones we have discussed so far. we will see more of them throughout the text. here, we will discuss equations that are in quadratic form, and rational equations that result in a quadratic. when solving linear trigonometric equations, we can use algebraic techniques just as we do solving algebraic equations. look for patterns, like the difference of squares, quadratic form, or an expression that lends itself well to substitution. see

For certain equations in quadratic form, we can either solve by substitution (as we have done above) or solve directly by treating the equation as quadratic in some other power of the variable (in the case of the equation of the following example, x 2 ). using a suitable substitution, is called an equation quadratic in form. such equations can be easily recognized by noticing that the power of an expression in one term is twice the power of the same expression in another term.

In this section, we'll come across equations that are in fact quadratic, but they may not look like it at first glance. we'll use either of the following methods to solve such equations: so the solutions for u are 16 or 4. so `x^2= 16` or `x^2= 4`. these give us: x = в€’4 or 4 x = в€’2 or 2 so the вђў the general form of a quadratic equation is ax2 + bx + c = 0. вђў to solve an equation means to fi nd the value of the pronumeral(s) or variables, which when substituted, will make the equation a вђ¦
