How do you solve 0 equals x squared minus ten x plus 16?

x^(2) - 10x + 16 = 0

Factors of '16', which are, 1,2,4,8,16. Select two numbers from this list that add/subtract to '10' . They are '2' and '8'.

Setting up brackets

( x 2)(x 8)

Since '16' is positive(+), then both signs must be the same. Since '10x' is negative (-) , then both signs are negative.

Hence

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

When

x - 2 = 0 x = 2

& when

x - 8 = 0

x = 8

So the two answers are ,2, & ,8, .
