When the value of X is - 3, the value of formula - 3x ^ 2 + ax-7 is - 2, then when x = - 1, the value of this formula is -

When the value of X is - 3, the value of formula - 3x ^ 2 + ax-7 is - 2, then when x = - 1, the value of this formula is -


X = - 3
-3*9-3a-7=-2
-34-3a=-2
-3a=32
a=-32/3
When x = - 1
-3x^2-32/3x-7
=-3+32/3-7
=2/3
