If it is =2c+9, go to AAAAAA if it is ()(4c+16)=2c+9, go to BBBBB
AAAAAAAAA =2c+9 =2c+9 times 4c+16 to both sides 1=(2c+9)(4c+16) distribute 1=8c^2+68c+144 minus 1 both sides 0=8c^2+68c+143 use quadratic formula c= or
BBBBBBBBBBBB (3/3)(4c+16)=2c+9 1(4c+16)=2c+9 4c+16=2c+9 minus 2c both sides 2c+16=9 minus 16 both sides 2c=-7 divide both sides by 2 c=-7/2 c=-3.5
