Answer»

substitute values in given equation answer is 0

a=2, b=4, c=1a^2-3bc+4ac2^2-3×4×1+4×2×14-12+8-8+80

a=2,b=4,c=1a^2-3bc+4ac2^2-3×4×1+4×2×14-12+8-8+80

a=2, b= 4, c= 1a^2 -3bc+4ac= (2)^2-3(4)(1)+4(1)(2)= 4-12+8= 12 -12= 0

a=2, b=4 ,c=1=a^2-3bc + 4ac=2^2-3×4×1+4×2×1=4-12+8=-8+8=0is the correct answer

Ans=(2×2)-(3×4×1)+(4×2×1)=4-12+8=12-12Answer =0
