(x-4)² + (x-2)² = x²

(x² - 8x + 16 ) + (x² - 4x + 4) = x

2x² -12x + 20 = x

2x²-12x + 20 - x = 0

2x² - 13x + 20 = 0

(2x-5) (x-4) = 0

2x-5 = 0

2x = 5

x = ⁵/₂


x-4 = 0

x = 4



so x₁ = ⁵/₂ , and x₂ = 4

I need to know how to do these
Allisa [31]

I'll do one, you can use it as a basis for your answer.

7x ^{2}    + 6 = 13

Subtract 6 from both sides to get X by itself.

7x ^{2}  = 7

Now we divide by 7 for both sides as well.

x {}^{2}  = 1

Now we find the square root of 1 to figure out X.

\sqrt{1}  = 1

Therefore, X=1.

my first answer in about a month. hope this helped.
