9x^{2}-4\left(y^{2}+4yx+4x^{2}\right)
Whakamahia te ture huarua \left(a+b\right)^{2}=a^{2}+2ab+b^{2} hei whakaroha \left(y+2x\right)^{2}.
9x^{2}-4y^{2}-16yx-16x^{2}
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te y^{2}+4yx+4x^{2}.
-7x^{2}-4y^{2}-16yx
Pahekotia te 9x^{2} me -16x^{2}, ka -7x^{2}.
9x^{2}-4\left(y^{2}+4yx+4x^{2}\right)
Whakamahia te ture huarua \left(a+b\right)^{2}=a^{2}+2ab+b^{2} hei whakaroha \left(y+2x\right)^{2}.
9x^{2}-4y^{2}-16yx-16x^{2}
