Question

(3х2 - 10x + 4) + (10х2 – 5х +8) can we this as a performance as a operation

Answer 1

Starting with the expression:

$(3x^2-10x+4)+(10x^2-5x+8)$

Ignore the parenthesis, since their coefficients are equal to 1:

$=3x^2-10x+4+10x^2-5x+8$

Use the commutative property of addition to change the order of the terms without changing the result of the sum. Bring like terms together:

$=3x^2+10x^2-10x-5x+4+8$

Add like terms:

$=13x^2-15x+12$

Therefore:

$(3x^2-10x+4)+(10x^2-5x+8)=13x^2-15x+12$
