Factor completely: 1)) a^2 - a - 20 2)) x^2 - 5x - 14 3)) b^2 + 12b + 32
Here's a some hint to do these type of factoring problems: 1-If the last term is negative (like #1 and 2), your factors will most likely be of the form (x+y)(x-z) 2-If the last term is positive, then your factors will be of the form (x+y)(x+z) OR (x-y)(x-z)
So for example in #1, since the last term is -20, then your factors will look like this: (a + ??)(a - ???)
now think of two numbers that multiply to -20 AND add up to -1....
Okay I got the first two I need help with the 3rd one
ok.. since the last term is +32, your factors will look like this: (b + ??) (b + ???) what two numbers can you think of that multiplies to 32 AND add up to 12 ?
Nvm I figured it out ! Thank you !
