4x2 - 6x-1 = 0
Help please

Good evening

x = (3 + √13)/4

or

x = (3 - √13)/4

Step-by-step explanation:

Firstly let’s calculate the discriminant Δ

Δ = (-6)² - 4(4)(-1) = 36 + 16 = 52 then √Δ = √52 = 2√13

then

x = (6 ± 2√13)/8

then

x = (3 ± √13)/4

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
