Someone just answer this for !

subtract 8y^2 - 5y + 7 from 2y^2 + 7y + 11.

the answer should be a polynomial in standard form.

(2y² + 7y + 11) - (8y² - 5y + 7) you can distribute the negative sign to the second expression and then combine the like terms

new expression: (2y² + 7y + 11) (-8y² + 5y - 7)

2y² and -8y² equals -6y²

7y and 5y equals 12y

11 and -7 equals 4

The answer is -6y² + 12y + 4

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

1 1/5
