Step-by-step explanation:

4a^2-b^2+6a^2-7b^2

=4 (-1)^2-(-3)^2+6 (-1)^2-7 (-3)^2

=4-9+6-63

=10-9-63

=1-63

=-2

x = 2

a= -1

b = -3

So,

        4a² - b² + 6a² - 7b²

=> 4(-1)² - (-3)² + 6(-1)² - 7(-3)²

   => 4(1) - (9) + 6(1) - 7(9)

       => 4 - 9 + 6 - 63

        => -5 + 6 - 63

            => 1 - 63

              => -62
