Question

(2x-1)(x+4)=0 need this question

Answer 1

Answer: you have 2 solutions for that equation, 1/2 and -4

Explanation:

(2x-1)(x+4)=0

2x^2+8x-x-4=2x^2+7x-4

use the formula for quadratic equations

x₁ and x₂ =-(7 (+-)
`\sqrt49+32`)/4=

we have x1= 1/2 and x 2=4

Answer 2

x = 1/2 or x = -4

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

x = 1/2 or x = -4
