Answer:
<h2>c).</h2>
5x² - 50x + 120
Factor out the LCF which is 5
We have
5( x² - 10x + 24)
Write 10x as a difference
That's
5( x² - 6x - 4x + 24)
Simplify
Factor the expression
5 [ x ( x - 6) - 4( x - 6) ]
Factor out x - 4 from the expression
We have the final answer as
<h2>5 ( x - 4)( x - 6)</h2>
<h2>f).</h2>
2x² - 6x - 260
Factor out 2 from the expression
That's
2 ( x² - 3x - 130)
Write 3x as a difference
That's
2 ( x² + 10x - 13x - 130)
Factorize the expression
2 [ x ( x + 10) - 13 ( x + 10) ]
Factor out x + 10 from the expression
We have the final answer as
<h2>2( x + 10)( x - 13)</h2>
Hope this helps you
