Answer:
GOOD MORNING HAVE A NICE DAY
Step-by-step explanation:
put x=3 ,y=4 ,z=5
4(3)²+9(4)²+16(5)²+12(3)(4)-24(4)(5)-16(3)(5)
=4(9)+9(16)+16(25)+12(12)-24(20)-16(15)
=36+144+400+144-480-240
=724-720
=4
Therefore the value of 4x²+9y²+16z²+12xy-24yz-16xz = 4
HOPE THIS STEPS EXPLANATION WILL HELP YOU
