Question

(3x²-1/5x+7/3)+(-1/4x²+1/3x-1/6)+(-2x²-1/2x+5)

Answer 1

Step-by-step explanation:

((7 • (a2)) + 14ab) + 7b2

STEP 2 :

Equation at the end of step2:

(7a2 + 14ab) + 7b2

STEP3:

STEP4:Pulling out like terms

 4.1     Pull out like factors :

   7a2 + 14ab + 7

Answer 2

$\huge\purple {\bf {\underline {Solution:-}}}$

${\tt {(3 {x}^{2} - \frac{1}{5x } + \frac{7}{3} ) + ( - \frac{1}{4 {x}^{2} } + \frac{1}{3x} - \frac{1}{6} ) + ( - 2 {x}^{2} - \frac{1}{2x} + 5)}}$

${\tt{⇒ \frac{45 {x}^{3} - 3 + 35x }{15x} + \frac{ - 3+ 4 {x} - 2 {x}^{2} }{12 {x}^{2} } + \frac{ - 4 {x}^{3} - 1 + 10x }{2x}}}$

$⇒ {\tt {\frac{4x(45 {x}^{3} - 3 + 35x) + 5( - 3 + 4x - 2 {x}^{2} ) + 30x( - 4 {x}^{3} - 1 + 10x) }{60 {x}^{2} }}}$

$⇒{\tt { \frac{180 {x}^{4} - 12x + 140 {x}^{2} - 15 + 20x - 10 {x}^{2} - 120 {x}^{4} - 30 x + 300 {x}^{2} }{60 {x}^{2} } }}$

$⇒{\tt { \frac{60 {x}^{4} + 430 {x}^{2} - 22x - 15 }{60 {x}^{2} }}}$
