Answer:
[tex] = 15 {x}^{2} + x - 2 \\ [/tex]
Step-by-step explanation:
[tex](3x - 1) \times (5x + 2) \\ 3x(5x + 2 ) - 1(5x + 2) \\ 15 {x}^{2} + 6x - 5x - 2 \\ = 15 {x}^{2} + x - 2[/tex]
hope this helps

good luck! have a nice day!
Given:
To find out:
Find the area ?
Solution:
Area = ( 3x - 1 ) × ( 5x + 2 )
= 3x ( 5x + 2 ) - 1 ( 5x + 2 )
= 15x² + 6x - 5x - 2
= 15x² + x - 2
Thus, the area is 15x² + x - 2 .
