Question

la solución de la ecuación 4× elevado a la 2 - 36 = 0 es:

a: 3y - 3
b: 4y - 4
c: 6y -6
d: 8Y - 8​

Answer 1

$4x {}^{2} - 36 = 0 \\ 4(x {}^{2} - 9) = 0 \\ x {}^{2} - 9 = 0 \\ x = \frac{ - b \frac{ + \sqrt{b { - 4ac}^{2} } }{2a} }{}$

$x = \frac{ - 0 \frac{ + \sqrt{0 { - }^{2} } - 4.1( - 9) }{} }{2.1}$

$x = \frac{ + \frac{6}{} }{2}$

$x = \frac{6}{2} \\ x = \frac{ - 6}{2}$

a)

3y-3
