Question

simplify 3×(4×-5)+3 ans find its value for 1 x= 3 and2 x=1/2

Answer 1

hello users............

solution:-
3(4x-5) + 3 = 12x -15 +3 = 12x -12

now ,
value for x=1/2 ,1 ,2 ,3

for x = 1/2
3(4x-5) + 3 = 12x-12
=> 12×1/2 -12 = 6 -12 = -6

for x= 1
=> 12×1-12 = 12-12 = 0

for x= 2
=> 12×2-12 = 24-12 = 12

for x = 3
=> 12×3-12 = 36 -12 = 24
