I hope this is help you and please follow me

Answer 2

$\red{\bold{\underline{\underline{QUESTION:-}}}}$

X=-2/3

$3 {x}^{2} - 13x - 10 = 0$

$\huge\bigstar\huge\tt\underline\red{ᴀɴsᴡᴇʀ }\bigstar$

$3 {x}^{2} - 13x - 10 = 0$

$3 {x}^{2} - 10x - 3x - 10 = 0$

$3 {x}^{2} - 3x - 10x - 10 = 0$

$3x(x - 1) + 10(x - 1)$

$(3x + 10)(x - 1)$

put x=-2/3

$3 ( - \frac{2}{3} ) + 10( - \frac{2}{3} - 1)$

$( - \frac{6}{3} + 10) (\frac{ - 2 - 3}{3} )$

$( - 2 + 10)( - \frac{5}{3} )$

$8 \times - \frac{ 5}{3} = - \frac{40}{3}$

Here is your answer..

hope it helps you..
