Question

find the roots of the following quadratic equation by factorization

${4x}^{2} + 5x = 0$
​

Answer 1

Answer:

Step-by-step explanation:

4x^2 + 5x =0

x(4x + 5) = 0

x = 0 OR 4x + 5 = 0

x = 0 OR 4x = - 5

x = 0 OR x = - 5 / 4.

FINDING ROOTS BY FACTORISATION :-

$4 {x}^{2} + 5x + 0= 0$

$4 {x}^{2} + 5x = 0$

$x(4x + 5) = 0$

↩NOW EITHER

$x = 0$

↩OR

$4x + 5 = 0$

LETS SOLVE THEM TO FIND x.

I)

$x = 0$

II)

$4x + 5 = 0$

$4x = - 5$

$x=-5÷4$

THE ROOTS ARE:0 AND -5÷4.

HOPE IT HELPS YOU
