Answer:
x = 1/2 or x = -4
Step-by-step explanation:
Since the product equals zero, use the zero product rule.
(2x - 1)(x + 4) = 0
2x - 1 = 0 or x + 4 = 0
2x = 1 or x = -4
Answer: you have 2 solutions for that equation, 1/2 and -4
(2x-1)(x+4)=0
2x^2+8x-x-4=2x^2+7x-4
use the formula for quadratic equations
x₁ and x₂ =-(7 (+-)[tex]\sqrt49+32[/tex])/4=
we have x1= 1/2 and x 2=4
