Question

find the roots of 3x^2+11x+10=0 by using quadratic formula​

Answer 1

Step-by-step explanation:

GIVEN the Question:

find the roots of 3x^2+11x+10=0 by using quadratic formula

Solve:-

According to the QUADRATIC FORMULA

${ax}^{2} + bx + c$

then ,

A = 3

B= 11

C = 10

QUADRATIC FORMULA:-

$\frac{ - b \frac{ + }{ - } \sqrt{ {b}^{2} - 4ac } }{2a}$

then Putting the value in formula,

$\frac{ - 11 \frac{ + }{ - } \sqrt{ { 11}^{2} - 4 \times3 \times 10 } }{2 \times 3}$

solving the Equation

$\frac{ - 11 \frac{ + }{ - } \sqrt{121 - 120} }{6} \\ \\ \frac{ - 11 \frac{ + }{ - } \sqrt{1} }{6}$

Once plus write,

$\frac{ - 11 + \sqrt{1} }{6}$

Once minus write

$\frac{ - 11 - \sqrt{1} }{6}$
