Question

solve 21x^2 +11x -2=0​

Answer 1

Answer:

21x^2+11x-2=0

21x^2+14x-3x-2=0

7x(3x+2)-1(3x+2)=0

(7x-1)(3x+2)=0

Answer 2

$\huge \mathfrak \red{</p><p>ANSWER : }$

$\bold{ {21x}^{2} + 11x - 2 = 0}$

$\bold{by \: middle \: term \: factorisation}$

$\bold{ {21x}^{2} + 14x - 3x - 2= 0}$

$\bold{taking \: common \: terms \: out}$

$\bold{7x(3x + 2) - 1(3x + 2)}$

$\bold{so \: the \: two \: factors \: are : }$

$\bold{(3x + 2)(7x - 1)}$
