Question

2y²+y-45 middle term factorization​

Answer 1

Answer:

y = -5 or y = 9/2

Step-by-step explanation:

$2 {y}^{2} + y - 45 = 0 \\ = > 2 {y}^{2} + 10y - 9y - 45 = 0 \\ = > 2y(y + 5) - 9(y + 5) = 0 \\ => (y + 5)(2y - 9) = 0 \\ = > y + 5 = 0 \: or \: 2y - 9 = 0 \\ = > y = - 5 \: or \: 2y = 9 \\ = > y = - 5 \: or \: y = \frac{9}{2}$
