Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

1.

( {2x}^{2} + 2x - 5) + ( {x}^{2} - 3x + 2) \\ = {2x}^{2} + 2x - 5 + {x}^{2} - 3x + 2 \\ = (2 {x}^{2} + {x}^{2} )(2x - 3x)( - 5 + 2) \\ = {3x}^{2} - x - 3

2.

2( {3y}^{2} - 4 ) + (4 {y}^{2} - 5y + 2) \\ = 6 {y}^{2} - 8 +( 4 {y}^{2} - 5y + 2) \\ = 6 {y}^{2} - 8 + 4 {y}^{2} - 5y + 2 \\ = (6 {y}^{2} + 4 {y}^{2} ) - 5y( - 8 + 2) \\ = 10 {y}^{2} - 5y - 6

3.

(3 {x}^{2} + 2x - 5) + 5( {x}^{2} - x - 2) \\ = 3 {x}^{2} + 2x - 5 + 5 {x}^{2} - 5x - 10 \\ = (3 {x}^{2} + 5 {x}^{2} )(2x - 5x)( - 5 - 10) \\ = 8 {x}^{2} - 3x - 15

4.

(4a - 10) - ( {a}^{2} + a + 3) \\ = 4a - 10 - {a}^{2} - a - 3 \\ = - {a}^{2} - 3a - 13

5.

( {2x}^{2} + 3x - 7) + 3 ({x}^{2} - 2x + 3) \\ = (2 {x}^{2} + 3x - 7) + (3 {x}^{2} - 6x + 9) \\ = 2 {x}^{2} + 3x - 7 + 3 {x}^{2} - 6x + 9 \\ = (2 {x}^{2} + 3 {x}^{2} )(3x - 6x)( - 7 + 9) \\ = 5 {x}^{2} - 3x + 2
