Question

3x^2+5x-1300=0 will be what....pls​

Answer 1

Answer:

3x^2 + 5x = 1300

x (3x +5) = 1300

3x + 5 = 1300/x

3x^2 = 1295

3x = √1295

3x= 35.986

x = 35.986/3

x = 11.953

Answer 2

${ \huge {\boxed {\boxed {\star\: \red{Answer}\: \star}}}}$

By splitting middle term

${3x}^{2} + 5x - 1300 \\ \\ {3x}^{2} + 65x - 60x - 1300 \\ \\ x(3x + 65) - 20(3x -65) \\ \\ (x - 20)(3x - 65) \\ \\ x = 20 \: and \: x = \frac{65}{3}$
