Question

8. Subtract the polynomials: (3x2 + 5x – 8) – (2x2 - 4x + 3)

please give steps!!

Answer 1

(3×2+5x-8)-(2×2-4x-3) = (6+5x-8)-(4-4x-3)

= 6+5x-8-4+4x+3

= -3+9x

Answer 2

`\\ \sf\longmapsto 3x^2+5x-8-(2x^2-4x+3)`

`\\ \sf\longmapsto 3x^2+5x-8-2x^2+4x-3`

`\\ \sf\longmapsto 3x^2-2x^2+5x+4x-8-3`

`\\ \sf\longmapsto x^2+9x-11`
