Mathematics
1 answer:
Alenkasestr [34]3 years ago
3 0

Answer:

Step-by-step explanation:

2x^{2}  + x - 4 = 0\\

divide by 2 throughout

x^{2}  + \frac{x}{2}  = \frac{4}{2}

x^{2} +2 * \frac{x}{4} +( \frac{1}{4}) ^{2}  = 2 + ( \frac{1}{4}) ^{2}\\

(x+\frac{1}{4} ^{2} ) = 2 + (\frac{1}{4} )^{2} \\

Hi, I'm often really slow at learning math and my condition makes it harder, can someone help me?
NARA [144]
The answer: 0, 4/5 and 5


Explanation: first, we factor out 2x and get: 2x(5x^2-29x+20)=0

In order for this equation to be equal to zero, either 2x must equal to zero or (5x^2-29x+20) must equal to zero

Having said that, if:
2x = 0
X=0

If:
(5x^2-29x+20) = 0
X=4/6, x=5
