Hi im having some difficulty in solving two quadratic equations shown below. i think i have answered the first one by using the quadratic formula
a) 2x²+15x+16=0 My Ans: -1.29 or -6.21
b) (2x-1)(3x+2) - (x+3)(2x+1) = 0 ?
Also a quick question, if a quadratic equation does not have a equal zero do i need to do something to the expression before trying to solve the quadratic.
Many thanks in advance
