Simplifying a(x2 + -4) + b(x2 + -4) = 0 Reorder the terms: a(-4 + x2) + b(x2 + -4) = 0 (-4 * a + x2 * a) + b(x2 + -4) = 0 (-4a + ax2) + b(x2 + -4) = 0 Reorder the terms: -4a + ax2 + b(-4 + x2) = 0 -4a + ax2 + (-4 * b + x2 * b) = 0 -4a + ax2 + (-4b + bx2) = 0 Solving -4a + ax2 + -4b + bx2 = 0 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '4b' to each side of the equation. -4a + ax2 + -4b + 4b + bx2 = 0 + 4b Combine like terms: -4b + 4b = 0 -4a + ax2 + 0 + bx2 = 0 + 4b -4a + ax2 + bx2 = 0 + 4b Remove the zero: -4a + ax2 + bx2 = 4b Add '-1bx2' to each side of the equation. -4a + ax2 + bx2 + -1bx2 = 4b + -1bx2 Combine like terms: bx2 + -1bx2 = 0 -4a + ax2 + 0 = 4b + -1bx2 -4a + ax2 = 4b + -1bx2 Reorder the terms: -4a + ax2 + -4b + bx2 = 4b + -4b + -1bx2 + bx2 Combine like terms: 4b + -4b = 0 -4a + ax2 + -4b + bx2 = 0 + -1bx2 + bx2 -4a + ax2 + -4b + bx2 = -1bx2 + bx2 Combine like terms: -1bx2 + bx2 = 0 -4a + ax2 + -4b + bx2 = 0 The solution to this equation could not be determined.
