Solve the equation. y^2-10y+16=0?

Question

Solve the equation. y^2-10y+16=0?

Answer 1

y^2-10y+16=0

(y-8)(y-2)=0

y=8 or y=2

Answer 2

y^2-10y+16 = 0

factor it

(y-8)(y-2) = 0

therefore either y -8 = 0 or y-2 = 0

answer:

y= 8 and y = 2

Answer 3

y^2 - 10y + 16 = 0

Factors of +16 that add to - 10 are -2 & -8

(x - 2)(x - 8) = 0

x = 2, 8

Answer 4

If you dont want to use factoring you can always use the quadratic equation. -b +or - Square root of b^2 -4(a)(c) all over 2(a)

In this specific problem 1 = a

-10= b

16 = c

Now plug it in and you will get your two answers

Answer 5

Use the quadratic formula.  You should get 8 and 2.
