Hello,

Step-by-step explanation:

2x² - 7x - 15 = (x - 5) (2x + 3)

x - 5 = 0 ⇔ x = 5

2x + 3 = 0 ⇔ x = -3/2

Answer:

[tex]x=-\frac{3}{2}[/tex] and [tex]x=5[/tex]

Step-by-step explanation:

[tex]2x^2-7x-15=0[/tex]

Factor by grouping.

[tex](2x+3)(x-5)=0[/tex]

Now apply the zero property

[tex]2x+3=0\\2x=-3\\x=-\frac{3}{2}[/tex]

and

[tex]x-5=0\\x=5[/tex]
