Question

ACTIVITY 3. Factor each expression using QUADRATIC TRINOMIALS.
a2-15a+56​

Answer 1

$Given \: Quadratic \: expression :$

$a^{2} - 15a + 56$

/* By splitting the middle term, we get */

$= a^{2} - 8a - 7a + 56$

$= a(a - 8) - 7(a-8)$

$= (a-8)(a-7)$

Therefore.,

$\red{ Factors \:of \: a^{2} - 15a + 56}$

$\green { = (a-8)(a-7)}$
