Question

simplify(a+1)(2a-1)-(3a-1)(a+3)​

Answer 1

SOLUTION

TO SIMPLIFY

$\sf{(a + 1)(2a - 1) - (3a - 1)(a + 3)}$

EVALUATION

$\sf{(a + 1)(2a - 1) - (3a - 1)(a + 3)}$

$\sf{ = (2 {a}^{2} - a + 2a - 1) - (3 {a}^{2} + 9a - a - 3 )}$

$\sf{ = (2 {a}^{2} + a - 1) - (3 {a}^{2} + 8a - 3 )}$

$\sf{ = (2 {a}^{2} + a - 1 - 3 {a}^{2} - 8a + 3 )}$

$\sf{ = - {a}^{2} - 7a + 2 }$

FINAL ANSWER

$\sf{(a + 1)(2a - 1) - (3a - 1)(a + 3)}$

$\sf{ = - {a}^{2} - 7a + 2 }$
