Question

solve by quadratic equation:

(4x-3)whole square + (4x+3)whole square =25

Answer 1

${(4x - 3)}^{2} + {(4x + 3)}^{2}$

$(16 {x}^{2} + 9 - 24x) + (16 {x}^{2} + 9 + 24x)$

$16 {x}^{2} - 24x + 9 + 16 {x}^{2} + 9 + 24x$

$16 {x}^{2} + 16 {x}^{2} - 24x + 24x + 9 + 9$

$32 {x}^{2} + 18$

this is the answer of your question.
