Question

4 x minus 3 whole square + 48 x is equal to 4 x + 3 whole square

Answer 1

$(4x - 3) {}^{2} + 48x = (4x + 3) {}^{2} \\ 4x {}^{2} - 3 {}^{2} - 2 \times 4x \times 3 + 48x = 4x {}^{2} + 3 {}^{2} + 2 \times 4x \times 3 \\ 16x - 9 - 24x + 48x = 16x + 9 + 24x \\ 16x - 24x + 48x - 16x - 24x = 9 + 9 \\ - 8x + 48x - 40x = 18 \\ 40x - 40x = 18 \\ = 18$
