3(x-5)^2+3(9-x^2)=2 Варианты ответа: A)-10,4; B)10,2; C)-10,2; D)-10; E)10;

Answer 1

Пошаговое объяснение:

$3(x-5)^2+3(9-x^2)=2\\\\3(x^2-10x+25)+27-3x^2=2\\\\3x^2-30x+75+27-3x^2-2=0\\\\-30x+100=0\\\\30x=100\\\\x=\frac{10}{3}\\\\x=3\frac{1}{3}$

Answer 2

3(х²-10х+25)+27-3х²-2=0

3х²-30х+75+27-3х²-2=0

-30х=-100

х=100/30=10/3=3 1/3

Answer 3

To solve the equation 3(x-5)^2 + 3(9-x^2) = 2, we can start by expanding and simplifying the equation:

3(x^2 - 10x + 25) + 3(9 - x^2) = 2 3x^2 - 30x + 75 + 27 - 3x^2 = 2 -30x + 102 = 2

Next, we isolate the variable by moving constants to the other side:

-30x = 2 - 102 -30x = -100

Finally, we solve for x by dividing both sides of the equation by -30:

x = (-100) / (-30) x = 10/3

None of the given answer options matches the solution 10/3. Therefore, none of the answer options A, B, C, D, or E is correct.
