x square +15x= -50 find the value of x

Answers

Answered by tripathyspandan23

Step-by-step explanation:

given quadratic equation is x²- 15x + 56 = 0

solution:-

x² - 15x + 56 = 0

=> x² -7x -8x + 56 = 0

=> x(x-7) - 8(x-7) = 0

taking (x-7) common..

=> (x-7)(x-8) = 0

=> (x - 7) and (x - 8) Are the two factors of given quadratic equation

and

x = 7 , 8 are the roots of equation

$x {}^{2} + 15x = - 50 \\ x {}^{2} + 15x + 50 = 0 \\ x {}^{2} + 5x + 10x + 50 = 0 \\ x(x + 5) + 10(x + 5) = 0 \\ (x + 5)( x + 10) = 0 \\ x + 5 = 0(or)x + 10 = 0 \\ x = - 5(or)x = - 10 \\ so \: the \: value \: of \: x \: is \: - 5 \: and - 10$
