Question

1 Subtract: a 2x2 + 3x + 1 from 4x2 + 7x + 6 b 7.2.​

Answer 1

$\large\bf{\underline\green{Correct\: question:-}}$

$subtract \: 2 {x}^{2} + 3x + 1 \:from \: 4 {x}^{2} + 3x + 1$

Hence ,

$= {4x}^{2} + 7x + 6 - (2 {x }^{2} + 3x + 1)$

$= {4x}^{2} + 7x + 6 - 2 {x}^{2} - 3x - 1$

$= {4x}^{2} - 2 {x}^{2} + 7x - 3x + 6 - 1$

$= 2 {x}^{2} + 4x + 5$
