Answer 1

Answer:

Step-by-step ex1

9

x2 − 8

3

x − 13

4

= 0

Factorization:

1

36

(4x2 − 96x − 117) = 0

Solutions based on quadratic formula:

x1  

= −(−96) − √ (−96)2 − 4×4×(−117)  

2×4

= 96 − 12 × √ 77  

8

≈ −1.162

x2  

= −(−96) + √ (−96)2 − 4×4×(−117)  

2×4

= 96 + 12 × √ 77  

8

≈ 25.162

Extrema:

Min = (12, −19.25)
