Negative exponets are like normal ones
ex. 2^-2=-4 another way to do it 2^-2=2^2 with a - so you can do 2^2=4 add the - and it becomes -4.
Equation: 53x + 460 = 1096
Solution 1096 - 460 = 53x
636/53=x
12=x

It is the last one, I just took the assignment on edg.
Step-by-step explanation:
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.
