Answer:
Step-by-step explanation:
b² - 4b - 12 = b² - 6b + 2b - 2*6
=b*(b -6) + 2*(b - 6)
= (b - 6) (b + 2)
b² - 4b - 12 = 0
(b - 6) (b + 2) = 0
b - 6 = 0 or b + 2 = 0
b = 6 or b = -2
<span>f=9/5 c + 32
or expressed in terms of f,
C=(5/9)(F-32)</span>
This product could be zero if one or both of the parenthesis are zero.
3x-9=0; 3x=9; x= 3
5x-3=0; 5x=3; x=3/5
The solution is { 3/5, 3}
136 - 3x = 40 +5x
136 - 40 = 5x + 3x
96 = 8x
12 = x
40 + 4(12)
40 + 48
88
