Solving Quadratic Equations by Factoring
(t-5)� = 2(5-t)
Modify:
(t-5)^2 = -2(t-5)
(t-5)^2 + 2(t-5) = 0
Factor:
(t-5)(t-5+2) = 0
(t-5)(t-3) = 0
t = 5 or t = 3
======================
Factoring
y� ( y + 1 ) -4y ( y + 1) -21 ( y + 1 )
(y+1)(y^2-4y-21)
(y+1)(y-7)(y+3)
-----------------------------------
Factoring Trinomial squares and differences of squares.
(y-5)� - 36q�
= [(y-5)-6q][y-5+6q]
==========================
