<img src="https://tex.z-dn.net/?f=%20t%5E%7B2%7D-6t%2B9-t%5E%7B2%7D%2B4t-4%3D%205" /> - 2t + 5 = 5 - 2t = 0
t = 0.
Desarrollamos los productos notables :
(t - 3)² - (t - 2)² = 5
t² - 6t + 9 - (t² - 4t + 4) = 5
t² - 6t + 9 - t² + 4t - 4 = 5
Se va t² : - 6t + 9 + 4t - 4 = 5 - 2t + 5 = 5 - 2t = 0
t = 0 / - 2
∴ t = 0.
