Question

factorise the following expression X square + 8 x + 50

Answer 1

Solution:-

given by:-

${x}^{2} + 8x + 50 \\ - {b}^{2} ( + - ) \sqrt{ { {b}^{2} - 4ac}} \times \frac{1}{2a} \\ \frac{ - 64( + - ) \sqrt{64 - 200} }{2} \\ \frac{ - 64( + - ) \sqrt{ - 136} }{2} \\ \frac{2( - 32 - + 4 \sqrt{34} }{2} \\ - 32( + - )4 \sqrt{34} \\ x = - 32 - 4 \sqrt{34} \\x = - 32 + 4 \sqrt{34}$
