(2x - 1)(x + 5) = 0

2x^2 + 10x - x - 5 = 0

2x^2 + 9x - 5 = 0

The value of b is 9.

2x^2 + 10x - x - 5 = 0

2x^2 + 9x - 5 = 0

The value of b is 9.

(4ab - 8a^2 + 12ac) ÷ 4a

= (4ab/4a) + (-8a^2/4a) + (12ac/4a)

= -2a + b + 3c

= (4ab/4a) + (-8a^2/4a) + (12ac/4a)

= -2a + b + 3c

3(2y - 8) - 2y(5 - y)

= (3)(2y) + (3)(-8) + 2y^2 + (-10y)

=6y+ (-24) + 2y^2 + (-10y)

=(2y^2) + (6y + (-10y)) + (-24)

=2y^2 - 4y - 24

= (3)(2y) + (3)(-8) + 2y^2 + (-10y)

=6y+ (-24) + 2y^2 + (-10y)

=(2y^2) + (6y + (-10y)) + (-24)

=2y^2 - 4y - 24
