Step-by-step explanation:
You should use a ^ to indicate an exponent. x^2 is the same as x².
x² + 9x + 20
Replace the x with (-5).
(-5)² + 9(-5) + 20 = 25-45+20 = 0
Then do the same with x = (-3):
(-3)² + 9(-3) + 20 = 9 - 27 + 20 = 2
You can do x = (-6)
Y = 9
7y - 10y = -3y
bring down the 9 = -18 so
-3y + 9 = -18
9 - 9 = 0
- 18 - 9 = - 27
- 3y ÷ - 3 = y
- 27 ÷ -3 = 9
therefore y =9
