In week 10 we were studying for the midterm. I studied unit 3 and a little of 4 because I did not do so well on those sections before.
Unit 3 was quadratic equations. The different ways to solve one is by factoring, quadratic formula and completing the square.
One thing that I did struggle with while studying was the word problems that made you put numbers into a quadratic equation.
Q1.) solve inequality quadratic.
i.) (x-2)(x-6)≤0
Ans.) y= -x² +10x-16
x>2, x<8xER
Q2.) -5x²>17x-12
Ans.) -5x²-17x+12
(-5x-3)(x+4)
x<3/5 , x>-4
