Question

Nomer 6 h,i dan j
mohon bantuannya :)

Answer 1

6h) gunakan rumus kecap

-b +- V(b^2 - 4ac)
= -1 +-V(1 -4(2)(-5))
= -1 +- V41
x1 = -1+V41
x2 = -1 -V41

6i) gunakan rumus kecap juga

-b +-V(b^2 -4ac)
= -3 +-V(9 -4(3)(-2))
= -3 +-V(9 + 24)
= -3 +-V33
x1 = -3 +V33
x2 = -3 -V33

6j ) gunakan rumus kecap juga

-b +- V(b^2 - 4ac)
= 4 +-V(16 - 4(5)(-3))
= 4 +- V(16 + 60)
= 4 +- V76
= 4 +- 2V19
x1 = 4 + 2V19
x2 = 4 - 2V19

ket tanda V = akar
