What is an x intercept of x^2-64

(8,0)   ( -8,0) are the x intercepts

Step-by-step explanation:

Factor

x^2 - 64

This is the difference of squares

(x-8) (x+8)

Set equal to zero to find the intercepts

x-8 = 0    x+8 =0

x= 8  x= -8

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)
