Question

4x2+3x=0 please solve this by using quadratic formula

Answer 1

Answer:

x= 0 and x=-3/4

Step-by-step explanation:

$4x^2 + 3x =0$

We need to solve this equation using quadratic formula.

The quadratic formula is:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

for the type of equation

$ax^2 +bx+c=0$

So, for our given equation:

a= 4

b= 3

c=0

putting values in the formula

$x=\frac{-3\pm\sqrt{9-0}}{8}\\x=\frac{-3\pm3}{8}\\x=\frac{-3+3}{8}\,and\, x=\frac{-3-3}{8}\\x=\frac{0}{8}\,and\, x=\frac{-6}{8}\\x=0\,and\, x=\frac{-3}{4}$[/tex]

so, x= 0 and x=-3/4.
