Simplifying (y + -5)(y + 9) = 15findy Reorder the terms: (-5 + y)(y + 9) = 15findy Reorder the terms: (-5 + y)(9 + y) = 15findy Multiply (-5 + y) * (9 + y) (-5(9 + y) + y(9 + y)) = 15findy ((9 * -5 + y * -5) + y(9 + y)) = 15findy ((-45 + -5y) + y(9 + y)) = 15findy (-45 + -5y + (9 * y + y * y)) = 15findy (-45 + -5y + (9y + y2)) = 15findy Combine like terms: -5y + 9y = 4y (-45 + 4y + y2) = 15findy Solving -45 + 4y + y2 = 15dfiny Solving for variable 'y'. Reorder the terms: -45 + -15dfiny + 4y + y2 = 15dfiny + -15dfiny Combine like terms: 15dfiny + -15dfiny = 0 -45 + -15dfiny + 4y + y2 = 0 The solution to this equation could not be determined.
