Answer 1

Answer:

1) 2x + 3 = 0

2x = 0 - 3

2x = -3

x = -3/2

2) 4x² - 5x + 3

If ,

x = 0

So ,

4(0)² - 5(0) + 3

4(0) - 0 + 3

0 - 0 + 3

0 + 3

3

3) (2x + 7)(4x - 1)

2x + 7 = 0

2x = 0 - 7

2x = -7

x = -7/2

4x - 1 = 0

4x = 0 + 1

4x = 1

x = 1/4

4) Sorry mate I don't know this answer

5) 9x³ + 2x² + 7

If ,

x = 2

So ,

9(2)³ + 2(2)² + 7

(9 × 8) + (2 × 4) + 7

56 + 8 + 7

56 + 15

71
