here, 7 cellphone,9 Tv, 12airconditioners = 8723
5 cellphone,7 Tv, 12airconditioners = 6523
or, 7,9,12=8723
-5,7,9=6523
______________
2,2,3=2191
then,
to make 4 cellphone , 4 tv set , 6 air conditioners add twice the answer ,

4x² + 2x - 30 = 0
<span>
factor out the GCF:
</span>2(2x² + x - 15) = 0
<span>
factor the trinomial completely:
2x</span>² + x - 15 = 0
2x² + 6x - 5x - 15 = 0
2x(x + 3) - 5(x + 3) = 0
(2x - 5)(x + 3) = 0
<span>use the zero product property and set each factor equal to zero and solve:
2x - 5 = 0 or x + 3 = 0
2x = 5 x = -3
x = 2.5
</span><span>The roots of the function are x=-3, x=2.5</span>
