n²-6n-7=0 what do i do?

Answers

Answer 1

Answer:

x = 7 and - 1

Step-by-step explanation:

f(x) = (x - 7) (x + 1)

x - 7 = 0

x - 7 + 7 = 0 + 7

x = 7

x + 1 = 0

x + 1 - 1 = 0 - 1

x = - 1

Use the value of the discriminant to determine the number and type of roots for the equation.

x^2 = 4x - 4

Answers

Answer:

d=0; discriminant equals zero

this means there is one real root for the equation

Step-by-step explanation:

the discriminant is d=b^2-4ac

so we can write our equation in the format to subsitute

ax^2+bx+c=0

x^2 = 4x - 4

so...

1x^2 - 4x + 4 = 0

so

a= 1

b=-4

c=4

now subsitute

d= b^2-4ac

d= -4^2-4(1)(4)

d=16-16

d=0

The discrimant equals zero.

when the discriminant equal zero we know that there is one real root for the equation.

Step-by-step explanation:

The best way to convert these into fractions is to multiply the decimal by what's in the denominator. Whatever number you get is what goes in the numerator.

1. For example, 0.6 x 10 = 6, hence the answer 6/10.

Even for ones like 8 where the decimal is 0.75, 0.75 x 4 = 3, which gives you 3/4.
