(2x² + 6x + 10) + (4x² + 2x + 3)
Remove the parentheses and bring like terms together ( as there's a positive outside the parentheses the terms inside keep their signs):-
= 2x^2 + 4x^2 + 6x + 2x + 10 + 3
= 6x^2 + 8x + 13 answer
(2x^2+6x+10)+(4x^2+2x+3)
2x²+4x² is 6x²
6x+2x is 8x
10+3 is 13
Answer is 6x²+8x+13
