Question

factorise it with step by step
-5x^-x+4​

Answer 1

Answer:

$\huge{\underline{\underline{Given→}}}$

• $\sf\green{Equation=-5x^2+x+4}$

$\huge{\underline{\underline{To\:Find→}}}$

$\sf\pink{→Factors\:of\:the\:given\:equation.}$

$\huge{\underline{\underline{Answer→}}}$

$- 5 {x}^{2} - x + 4 \\ = - 5 {x}^{2} - 5x + 4x + 4 \\ = - 5x(x + 1) + 4(x + 1) \\ = ( - 5x + 4)(x + 1)$

$\sf{\boxed{\boxed{\red{→x=-1\:and\:=\frac{4}{5}✔}}}}$

$\sf\purple{So\:the\:factors\:are→}$

$\sf\blue{(-5x+4)\:and\:(x+1)}$

$\sf\purple{and\:the\:roots\:are→}$

$\sf\blue{x=-1\:and\:x=\frac{4}{5}}$
