Question

(5x – 6) (2x – 3) + (3x + 5)²

Answer 1

Question :-

Simplify it .

→(5x -6)(2x -3)+ (3x+5)²

Answer :-

→ 19x² +3x + 43

Used formula :-

→ (a+b)² = a² + b² + 2ab

Explanation :-

We have ,

→(5x -6)(2x -3)+ (3x+5)²

→ 10x²-15x -12x+18 + (3x+5)²

→ 10x² - 27x +18+9x² +25 +30x

→ 19x² +3x + 43

hope it will help you.

Answer 2

$\huge\bf\red{SoLutiOn:-}$

(5x - 6)(2x - 3) + (3x + 5)²

5x(2x - 3) -6(2x - 3) + (9x² + 30x + 25)

10x² - 15x - 12x + 18 + 9x² + 30x + 25

10x² + 9x² - 27x + 30x + 25 + 18

19x² + 3x + 43

$\huge{\boxed{\boxed{\boxed{\red{19{x}^{2} + 3x + 43}}}}}$
