Question

Which expression is a factor of 10x2 + 11x + 3?
OX-3
0 2x + 1
0 5x - 3
O 10x + 3​

Answer 1

Answer:-

$\red{\bigstar}$ Factor of given expression $\large\leadsto\boxed{\rm\orange{Option.B \rightarrow(2x+1)}}$

• Given:-

$\sf 10 x^2 + 11x + 3$

• To Find:-

Factor of the given expression

• Solution:-

$\sf 10x^2 + 11x + 3$

Splitting the middle term:-

→ $\sf 10x^2 + 5x + 6x + 3$

→ $\sf 5x(2x + 1) + 3(2x + 1)$

→ $\sf (2x + 1) ( 5x + 3)$

Therefore,

$\bf(2x + 1)$ and $\bf(5x + 3)$ are the factors of the given expression.

Hence,

Option B → (2x +1)
