Question

Simultaneous equation
0=2a^2+2b
8=4a^2+4b
X=
Y=

Answer 1

What's the question?

Answer 2

can u solve it as i tried and codnt

Answer 3

So you're trying to find a and b that satisfy the above equations?

Answer 4

yes

Answer 5

oh lol i wrote x and y instead of a and b

Answer 6

It doesn't seem to work. No values of a and b works

Answer 7

crap i must have somin wrong let me tell the word that i changet into the equation

Answer 8

the curve y=ax^2+bx passes through (2,0) and (4,8) find a and b

Answer 9

0 = 4a +2b
8 =16a + 4b

0 = 4a +2b
0 = 8a + 4b

8=16a +4b
- 0 = 8a+4b
8 = 8a
a =1
b = -2
