Question

if x=-2&x=3/4are the solutions to the equation hx^2+kx-6=0,find the value of h and k
​

Answer 1

Answer:

very poor in maths bro what to do, sorry

Answer 2

Step-by-step explanation:

putting x=2

4h+2k=6. ( dividing by 2 )

2h+k=3—(1)

putting x=3/4

9/16h+3/4k =6

36/16+3k=24

9/4h+3k=24

9h+12k=96—(2)

from eq (1),

h=3-k/2—(3)

putting in eq (2)

9(3-k/2)+12k=96

27-9k/2+12k=96

27-9k+24k=192

27+15k=192

15k=192-27

15k=165

k=11

putting k=11 in eq (3)

h=3-k/2

=3-11/2

-8/2

=-4

h=-4.
