5хх²-7х×4х²+0,5×2хх³+8-х= 3ав²-8х+4в²а+5ва×3в=

Let's solve the provided equations step-by-step. ### Equation 1: **\(5xx² - 7x \times 4x² + 0.5 \times 2xx³ + 8 - x = 0\)** Let's simplify each term: 1. **\(5xx²\)** = \(5x^3\) 2. **\(-7x \times 4x²\)** = \(-28x^3\) 3. **\(0.5 \times 2xx³\)** = \(x^4\) 4. Combine the constant and the linear term: **\(8 - x\)**. Now substitute these back into the equation: \[ 5x^3 - 28x^3 + x^4 + 8 - x = 0 \] Combine like terms for \(x^3\): \[ x^4 - 23x^3 - x + 8 = 0 \] ### Equation 2: **\(3ab² - 8x + 4b²a + 5ba \times 3b = 0\)** Again, we'll simplify each term: 1. **\(3ab²\)** remains \(3ab²\) 2. **\(-8x\)** remains as is 3. **\(4b²a\)** remains as is 4. **\(5ba \times 3b\)** = \(15ab²\) Now substitute these back into the equation: \[ 3ab² - 8x + 4b²a + 15ab² = 0 \] Combine like terms for \(ab²\): \[ (3ab² + 15ab²) - 8x + 4b²a = 0 \] This simplifies to: \[ 18ab² - 8x + 4b²a = 0 \] ### Summary of Equations Now we have simplified to: 1. **\(x^4 - 23x^3 - x + 8 = 0\)** 2. **\(18ab² + 4b²a - 8x = 0\)** If you need further help with solutions or specific methods to solve these equations, let me know!
