Question

नाइन एक्स स्क्वायर प्लस 5 एक्स माइनस 26 ​

Answer 1

${9}^{2} + 5 {x}^ - 26$

solution :-

26×9= 234

factors of 234 = 2×3×3×13

when we mulply 18 and 13 we will find 234 a nd when we substract 13 from 18 we will find 5

so,

$9 {x}^{2} + (18 - 13)x - 26 \\ 9 {x}^{2} + 18x - 13x - 26 \\ 9x(x + 2) - 13(x + 2) \\ (9x - 13)(x + 2)$

if question is says that find the value of x then

if 9x-13=0

x=13/9

,if x+2=0

x=(-2) answer
