Question

factor :- 2x^2+3x-11​

Answer 1

Answer:

the answer is x=( -3+- √97)/ 4

Answer 2

The given equation f(x) = 2x² + 3x -11

i.e., a = 2 , b = 3 , c = -11

Now, The Formula of quadratic equation is used to find the factor is

f(x) $= \frac{ - b±  \sqrt{ {b}^{2} - 4ac } }{2a}$

$= \frac{ - 3±  \sqrt{ {(3)}^{2} - 4 \times 2 \times ( - 11)} }{2 \times 2}$

$= \frac{ - 3 ± \sqrt{9 + 88} }{4}$

$= \frac{ - 3 + \sqrt{97} }{4} or \frac{ - 3 - \sqrt{97} }{4}$
