Factoring 24y215024y^2 - 150

To factor the binomial 24y215024y^2 - 150 completely, first check for a greatest common factor (GCF). Both terms share a GCF of 66. Factoring it out gives 6(4y225)6(4y^2 - 25). Inside the parentheses, the binomial is a difference of squares because 4y2=(2y)24y^2 = (2y)^2 and 25=5225 = 5^2. Write it as a product of conjugates: (2y5)(2y+5)(2y - 5)(2y + 5). The completely factored expression is 6(2y5)(2y+5)6(2y - 5)(2y + 5). Neither binomial can be factored further. Multiply the factors to verify the result.
