Hello, I have this problem that I'm trying to understand how to solve, but when I put it in the solver the answer doesn't match the textbook. b^2+7ab-4a-5 when a=1/2 b=-6 -6^2+7(1/2)(-6)-4(1/2)-5 The book says the answer is 8 and I'm trying to learn how to approach this expression with a fraction so I used your math solver and it says -64. Can someone please help me. Thank you!
