Your "<span>h (x)=x 2 squared +6x-3" is ambiguous.  If you meant "x squared," then you need only write x^2  OR  "x squared," but NOT "x 2 squared."
I will assume that by  "</span><span>h (x)=x 2 squared +6x-3" you actually meant:
</span><span>h(x)=x^2 +6x-3.  To find h(3), subst. 3 for x:  h(3) = (3)^2 + 6(3) - 3, or
h(3) = 9 + 18 - 3, or h(3) = 24.</span>
        
             
        
        
        
General formula for area of triangle is  .
