Answer:
3. 4a(a + 1) - 15
step-by-step explanation:
1. (x +y)² + 11 (x + y) + 30
= x + y {(x +y) + 11} + 30
2. (a - b)² - 16(a - b) + 60
= (a - b){(a - b) - 16} + 60
3. 4a² + 4a - 15) - 15
4. 2x² + 5x + 2
= x(2x + 5) + 2

Answer:
Y=- 6
3(y-5)+2=5
multiply
3y-15+2=5
add
3y-13=5
add pos 13 to the neg 13 to
cancel it out and add +13 to 5
3y=18
divide -3 to pos 3 and 18 to cancel it out
y= -6
