Question

x square+15x = - 50​

Answer 1

Answer:

${x}^{2} + 15x = - 50 \\ \\ \\ = > {x}^{2} + 15x + 50 = 0 \\ \\ = > {x}^{2} + 5x + 10x + 5 0= 0 \\ \\ = > x(x + 5) + 10(x + 5) \\ \\ = > (x + 10)(x + 5) = 0 \\ \\ \\ = > x = - 10 \\ x = - 5$

${x}^{2} + 15x = - 50$

shifting -50 to L.H.S

${x}^{2} + 15x + 50 = 0$

${x}^{2} + 10x + 5x + 50 = 0$

taking x common

$x(x + 10) + 5(x + 10)$

$(x + 10)(x + 5)$

thus, the factors are x+10 and x+5

value of x that can satisfy equation are -10 and -5
