Question

Subtract: 4pq- 5q power2- 3p power2 from 5p power2 + 3q power2 - pq ​

Answer 1

Answer:

$\mathtt\purple{ANSWER:-}$

$\mathtt{ = 4pq - {5q}^{2} - {3p}^{2} \: from \: {5p}^{2} + {3q}^{2} - pq }$

$\mathtt{ = {5p}^{2} + {3q}^{2} - pq - (4pq - {5q}^{2} - {3p}^{2}) }$

$\mathtt{ = {5p}^{2} + {3q}^{2} - pq - 4pq + {5q}^{2} + {3p}^{2} }$

$\mathtt\purple{COMBINE \: ALL \: LIKE \: TERMS}$

$\mathtt{ = {5p}^{2} + {3p}^{2} - pq - 4pq + {5q}^{2} + {3q}^{2} }$

$\mathtt{ = {8p}^{2} - 5pq + {8q}^{2} }$

Answer 2

Answer:

_________________________

8p²+ 8q²-5pq

_________________________

Step-by-step explanation:

given:

$4pq - 5q^{2} - 3p^{2}$_________________(1)

$5p^{2} + 3q^{2} - 4pq$________________(2)

_________________________

according to the question:

subtract (1) from (2)

_________________________

solution :

⇒   $5p^{2} + 3q^{2} -pq - (4pq -5q^{2} - 3p^{2} )$

⇒    $5p^{2} + 3q^{2} - pq - 4pq + 5q^{2} + 3p^{2}$

⇒     $( 5p^{2} + 3p^{2} ) + (3q^{2} + 5q^{2}) + (-pq - 4pq)$   (by grouping like terms)

⇒    $8p^{2} + 8q^{2} - 5pq$

_________________________

hence the answer is :

8p²+ 8q²-5pq
