Question

calcule a equação L(x) = -(x-8)² - 8(x-8)

Answer 1

L(x)=-(x8)^2-8(x-8)
L(x)=-(x)^2-2(x)(8)+(8)^2-8x-64
L(x)=-x^2-16x+64-8x-64
L(x)=-x^2-16x-8x+64+64
L(x)=-x^2-24x+128(-1)
L(x)= x^2+24x-128
L(x)= a= 1,b=24,c=-128
L(x)=x=-24+,-\/24^2-4(1)(-128)/2(1)
L(x)=x=-24+,-\/576-4(-128)/2
L(x)=x=-24+,-\/576+512/2
L(x)=x=-24+,-\/1088/2
L(x)=x=-24+,-32,98/2
L(x)=x1=-24+32,98/2
L(x)=x1=8,98/2
L(x)=x1=4,49
L(x)=x2=-24-32,98/2
L(x)=x2=-56,98/2
L(x)=x2=-28,49
