Question

If x=2/3
and x = -2 are roots of quadratic
equation mx² + 4x + n=0, then the values
..... and ........ respective
please explain it​

Answer 1

Answer:

m = 3;

n = -4

Step-by-step explanation:

$(x - \frac{2}{3} ) \times (x - ( - 2)) = 0$

$(3x - 2)(x + 2) = 0$

$3 {x}^{2} + 6x - 2x - 4$

$3 {x}^{2} + 4x - 4 = 0$

m = 3;

n = -4
