Question

Uhh help me again lmao

Answer 1

Answer:

(G) 4x²+5x+2

because :

equation :

6x²+5-2x²+4x-3+x (in sequence)

6x²-2x² + 4x +x + 5-3

4x² + 5x +2

Answer 2

Answer:

(G) 4x^2 + 5x + 2 is correct.

Step-by-step explanation:

Long method (for explanation purposes) -

First, group the terms according to power. 6x^2 and -2x^2 have a power of 2, 4x and x have a power of 1, and 5 and -3 have a power of 0.

Now, rearrange the terms of the polynomial according to decreasing power. This gives

(6x^2 - 2x^2) + (4x + x) + (5 - 3) = 4x^2 + 5x +2, which is the answer given in (G).

Short method (to use in an objective test) -

Consider the terms of any power. In this question, take those with power 2 preferably.

These terms are 6x^2 and - 2x^2 which when added together gives 4x^2.

Notice in the options that only (G) has the term 4x^2.

Hence, (G) is the correct answer.
