Question

4ײ+3×=22
con fórmula general pliis:(​

Answer 1

Respuesta:

Explicación paso a paso:

a= 4  b= 3 c= -22

-b +- $\frac{\sqrt{b^{2}-4ac } }{2a}$

-3 +- $\frac{\sqrt{9+352} }{8} }$

$\frac{-3+19}{8} = 2$

o

$\frac{-3-19}{8} = -11/4 = -2,75$

Answer 2

Respuesta:

4x2+3x−22=0  

(4)⋅x2+(3)⋅x+(−22)=0

x=−(3)±(3)2−4⋅(4)⋅(−22)−−−−−−−−−−−−−−−−−√2⋅(4)

x=−3±9−(−352)−−−−−−−−−−√8

x=−3±361−−−√8

x=−3±(19)8

x1=168=(8)⋅(2)(8)=2

x2=−228=(2)⋅(−11)(2)⋅(4)=−11⁄4
