Question

if x is equal to 2 and x is equal to 3 are the root of quadratic equation a x square + 7 x + 6 is equal to zero find the value of a and b​

Answer 1

Answer:

as we have ax square+7x+6=0

put 2 as x in equation

4a+14+6=0

a=(-5)

Answer 2

Answer:

a = -3 ; a = -5

Step-by-step explanation:

$ax {}^{2} + 7x + 6 = 0$

When x = 2,

$4a + 14 + 6 = 0 \\ 4a + 20 = 0 \\ 4a = - 20 \\ a = - 5$

When x = 3,

$9a + 21 + 6 = 0 \\ 9a + 27 = 0 \\9 a = - 27 \\ a = - 3$

Since there are noe specific conditions for a,

a = -3,-5.
