3у*7-3у*5у+2*7-2*5у=21у-15у^2+14-10у= -15y^2+11у+14

Answer 2

To simplify the expression (3y + 2) • (7 - 5y), you can use the distributive property, also known as FOIL (First, Outer, Inner, Last). Here's the step-by-step process:

1. First, multiply the terms from the first parentheses with the terms from the second parentheses:

(3y) • (7) = 21y (3y) • (-5y) = -15y^2 (2) • (7) = 14 (2) • (-5y) = -10y

2. Now, combine the like terms:

21y - 15y^2 + 14 - 10y

3. Finally, simplify the expression by combining like terms:

(21y - 10y) - 15y^2 + 14

= 11y - 15y^2 + 14

So, the simplified expression is 11y - 15y^2 + 14.
