Answer:

1156

Step-by-step explanation:

We know that,

( a + b ) ² =  a² + 2ab + b²

We can follow the same method to find the value of this.

12² + 22²

( 12 + 22 ) ²

12² + 2 × 12 × 22 + 22²

144 + 24 × 22 + 484

144 + 528 + 484

672 + 484

What is the quotient (6x4 + 15x3 − 2x2 + 10x − 4) ÷ (3x2 + 2)?
VMariaS [17]

The given problem is :

(6x^4 + 15x^3 − 2x^2 + 10x − 4) ÷ (3x^2 + 2)?

now we can write expression (6x^4 + 15x^3 − 2x^2 + 10x − 4) as

(6x^4 + 4x^2 + 15x^3 + 10x - 6x^2 -4)

we have somehow arrange the expression in a way that 3x^2 + 2 is common

now the expression comes out to be

2x^2(3x^2 + 2) + 5x(3x^2+2) -2(3x + 2) / (3x^2+2)

After dividing final result comes out to be (2x^2 + 5x -2)
