Question

Add the following polynomials 4x² + 5x + 6;x² + 1;5x³ + 4x +3​

Answer 1

Step-by-step explanation:

$\huge{ \color{red}{ \boxed{ \color{blue}{hello}}}}$

Your question:

$( {4x}^{2} + 5x + 6) + ( {x}^{2} + 1) + (4x + 3)$

Your answer:

$= 4 {x}^{2} + 5x + 6 + {x}^{2} + 1 + 4x + 3$

[ open the parentheses ]

$= (4 {x}^{2} + {x}^{2} ) + (5x + 4x) + (6 + 1 + 3)$

[ group the common ones ]

$= 5 {x}^{2} + 9x + 10$

[ now, add all ]

Your final answer:

$\huge{ \color{red}{ \boxed{ \color{blue}{5 {x}^{2} + 9x + 10 }}}}$
