Question

7x-x elevado a 2-6=0 formula de baskara

Answer 1

Bom dia

7x- x^2 -6 = 0

-x^2+ 7x- 6= 0 . (-1)

x^2-7x+ 6= 0

▲= 49-4.1.6
▲= 49-24
▲= 25

x= 7+_5 / 2

x1= 6
x2= 1

Answer 2

7x-x²-6=0

x²-7x-6=0

Utilizaremos a equação de bhaskara -b+-√b²-.4.a.c /2a

-(-7)+-√7²-.4.1.-6

7+-√49-.(-24) /2

7+-√25/2

7+-5/2

x'=6

x"=1
