Verified answer

G(x) = x² + 7x - 3
h(x) = x² + 11x + 9

Diketahui g(m) = h(m)
g(m) = m² + 7m - 3 = h(m) = m² + 11m + 9

a. Nilai m
m² + 7m - 3 = m² + 11m + 9
        7m - 11m = 3 + 9
        - 4m = 12
            m = -3

b. g(4m) - h(4m)
    g(-12) - g(-12)
    (-12)² + 7(-12) - 3 - (-12)² - 11(-12) - 9
    (7-11)(-12) - 3 - 9
    (-4)(-12) - 12
    (-4 +1) (-12)
    (-3)(-12)
 = 36
