Simplifying (-7 + -2z)(-7 + 2z) = equation Multiply (-7 + -2z) * (-7 + 2z) (-7(-7 + 2z) + -2z * (-7 + 2z)) = equation ((-7 * -7 + 2z * -7) + -2z * (-7 + 2z)) = equation ((49 + -14z) + -2z * (-7 + 2z)) = equation (49 + -14z + (-7 * -2z + 2z * -2z)) = equation (49 + -14z + (14z + -4z2)) = equation Combine like terms: -14z + 14z = 0 (49 + 0 + -4z2) = equation (49 + -4z2) = equation Solving 49 + -4z2 = aeinoqtu Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '-49' to each side of the equation. 49 + -49 + -4z2 = -49 + aeinoqtu Combine like terms: 49 + -49 = 0 0 + -4z2 = -49 + aeinoqtu -4z2 = -49 + aeinoqtu Divide each side by '-4'. z2 = 12.25 + -0.25aeinoqtu Simplifying z2 = 12.25 + -0.25aeinoqtu Reorder the terms: -12.25 + 0.25aeinoqtu + z2 = 12.25 + -0.25aeinoqtu + -12.25 + 0.25aeinoqtu Reorder the terms: -12.25 + 0.25aeinoqtu + z2 = 12.25 + -12.25 + -0.25aeinoqtu + 0.25aeinoqtu Combine like terms: 12.25 + -12.25 = 0.00 -12.25 + 0.25aeinoqtu + z2 = 0.00 + -0.25aeinoqtu + 0.25aeinoqtu -12.25 + 0.25aeinoqtu + z2 = -0.25aeinoqtu + 0.25aeinoqtu Combine like terms: -0.25aeinoqtu + 0.25aeinoqtu = 0.00 -12.25 + 0.25aeinoqtu + z2 = 0.00 The solution to this equation could not be determined.
