Answer:

see explanation

Step-by-step explanation:

A quadratic has a squared variable , this equation does not

The general form of a quadratic equation is

ax² + bx + c = 0 ( a ≠ 0 )

The equation here

x = 5 - 3x ( add 3x to both sides )

4x = 5 is not in quadratic form and is a linear equation, since the variable is x not x²

Answer:Although the Quadratic Formula always works as a strategy to solve quadratic equations, for many problems it is not the most efficient method. Sometimes it is faster to factor or complete the square or even just "out-think" the problem. For each equation below, choose the method you think is most efficient to solve the equation and explain your reason. Note that you do not actually need to solve the equation. a. x2+7x−8=0x  

2

+7x−8=0, b. (x+2)2=49(x+2)  

2

=49, c. 5x2−x−7=05x  

2

−x−7=0, d. x2+4x=−1x  

2

+4x=−1.
