Given the expression 2x^2 + 3x + c, what value could be filled in for c to create an equivalent expression that is factorable using integers? Once you have found 1 value, what is the smallest value you can find that creates a true statement? How do you know it is the smallest value?

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
