Tolong jawab ya; Fungsi g dan h ditentukan dengan rumus g(x)= x²+7x-3 dan h(x)= x²+11x+9. Jika nilai g(m) = h(m), tentukan:A. nilai MB. g(4m) - h(4m)

g(m) = h(m)
m² + 7m - 3 = m² + 11m + 9
0 = 4m + 12
-4m = 12
m = -3

g(4m) - h(4m)
= g(4(-3)) - h(4(-3))
= g(-12) - h(-12)
= ((-12)² + 7(-12) - 3) - ((-12)² + 11(-12) + 9)
= (144 - 84 - 3) - (144 - 132 + 9)
= -87 + 123
= 36
