hi again so first, you need to add 5 to both sides of the equation, so it becomes 2x^2 = 32 next, you divide BOTh sides by 2 because you are going reverse order of operations. this gets rid of the 2 in front of the x^2. so the equation becomes x^2 = 32/2

hi there, first look at c, which is -20. what 2 numbers, when multiplied, equal -20 and add up to positive 8? well, 10 x -2 = -20, and 10-2 = positive 8, so it would become (x+10)(x-2) = 0 set both of these equal to 0 and solve, so x+10 = 0 subtract ten
