interpret what the three solutions represent
Transcribed Image Text:Solution 1
y = (x +3)(2x − 5)
y = 2x² + 6x - 5x - 15
y = 2x2 + x – 15
= 2(2x)2−1 +1-0
y' = 4x + 1
y
Solution 2
y = (x +3)(2x − 5)
y = (x + 3)(2) + (2x − 5)(1)
= 2x+6+2x - 5
y' = 4x + 1
y
Solution 3
y
y = (x +3)(2x − 5)
y = 2x2 + x – 15
= 2(2x)2−1 +1-0
y' = 4x + 1
