1) x² - 9z6 is not a clear expression. It seems like there might be a typo. Please provide the correct expression for further assistance.
2) 25в(6 степ) + 10в(3 степ)а² + а²= 25в^6 + 10в^3а² + а²
3) Решите уравнение: x-3(x+1)=4x - 3x - 3 = 4-2x - 3 = 4-2x = 7x = -7/2

2) 25в(6 степ) + 10в(3 степ)а² + а²
= 25в^6 + 10в^3а² + а²
3) Решите уравнение: x-3(x+1)=4
x - 3x - 3 = 4
-2x - 3 = 4
-2x = 7
x = -7/2
