Question

Multiply (5x+3y) and (4x+ 5y) to each
other,​

Answer 1

Answer:

20x² + 37xy + 15y²

Step-by-step explanation:

(5x + 3y) (4x + 5y)

multiply the first numbers first : 5x multiplied by 4x

then, multiply the first number from the first bracket with the second number from the second bracket : 5x multiplied by 5y

next, multiply the second number from the first bracket with the first number from the second bracket : 3y multiplied by 4x

lastly, multiply the second number from the first bracket with the second number from the second bracket : 3y multiplied by 5y

= 20x² + 25xy + 12xy + 15y²

= 20x² + 37xy + 15y²

Hope this helped. It is better to write it down and draw curve lines above which numbers to multiply next.
