Question

Simplify:(4x2 - 2x) - (-5x2 - 8x).
​

Answer 1

Answer:

Step-by-step explanation:

(4x^2-2x) -(5x^2-8x)

=4x^2-2x-5x^2+8x   [Minus sign outside bracket changes all the signs once bracket has been opened]

= -x^2+6x

Answer 2

$\huge\mathfrak{Answer}$

$\huge\sf{18 + 6x }$

$\huge\sf{solution:}$

$We use here BODMAS rule and solved it simply$

$= (4 \times 2 - 2x) - ( - 5 \times 2 - 8x)$

$= (8 - 2x) - ( - 10 - 8x)$

$= 8 - 2x + 10 + 8x$

$Taking like term togther$

$= 10 + 8 + 8x - 2x$

$= 18 + 8x - 2x$

$= 18 + 6x$
