1.) 6x + 3x^2 - x - x^2 2.) 5 + 2x + y + 2x - 1
3.) 2x + 2y + x^2 - x + x^2

please solve this

1. 6x + 3x² - x - x²

3x² - x² + 6x - x 2x² + 5x

2. 5 + 2x + y + 2x - 1

2x + 2x + y + 5 - 14x + y + 4

3. 2x + 2y + x² - x + x²

x² + x² + 2x - x + 2y 2x² + x + 2y

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
