Question

Solve the following quadratic equation by factorization. x2 + x – 20 = ​

Answer 1

Answer:

3x-20

Step-by-step explanation:

2x+x=3x

Answer 2

$\mathtt\green {Correct \: Question :-}$

• $\sf \rightarrow\: {x}^{2} + x - 20$

$\mathtt\red{To \: Do:-}$

• $\sf \rightarrow{factorise}$

$\mathtt \pink{Let's \: Start:-}$

$\sf : \rightarrow solving \: by \: middle \: split \: term\: method.$

$\sf = {x}^{2} + 10x - 10x - 20$

$\sf = x(x + 10) - 10(x + 10)$

$\sf \red= \red ( \red x \red + \red 1 \red0 \red) \blue( \blue x \blue - \blue1 \blue0 \blue)$
