Question

pls Tell the answers how much ever u know by working

Answer 1

Answer:

Step-by-step explanation:

2. 5x(x² + 3x - 2) + 4(x - 3)

= 5x³ + 15x² - 10x + 4x - 12

= 5x³ + 15x² - 6x - 12

*Imputing the values*

= 5(-1)³ + 15(-1)² - 6(-1) - 12

= -5 - 15 + 6 - 12

= -26

(II) 1. i)

= (3x + 4)(3x - 5)

= (3x)² + (4 + (-5)) 3x + 4*-5

= 9x² - 3x - 20

ii)

= 97 x 103

= (100 - 3) (100 + 3)

= (100) ²- (3)²

= 10000 - 9

= 9991

Answer 2

Step-by-step explanation:

2. 97×103

(100-3) (100+3)

(100)^2 - (100)^3

10000-9

= 9991 10000

- 9

9991
