Question

Simplify:(4x2 - 2x) - (-5x2 - 8x).

Answer 1

Answer:

hiii

your answer is here !

Step-by-step explanation:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer 2

Answer:

(4×2-2×)-(-5×2-8×)

=(8-2×)+(10-8×).as - minus minus- = +plus

now take out x digit no in one side and normak digit no in one side we get:-

8-2x+10-8x

now add/subtract these no with each other but u must know that (x) will be added or subtracted by (x) no only.and normal no with normal no.

Now,

8+10-2x-8x=0

18-10x=0 ( as we know -- -- =+)

-10x=-18

x=-18/10

so,

x=9/5.

one more to know that if greater no is in minus then there will be a minus sign before the digit.

-- -- = +

+ -- = --

+ + = +

-- + = --
