Study Notes

Algebraic Products

The product of (-x-4)(5x-5) is -5x²-15x+20.
The product of (-4x+3)(-2x+5) simplifies to 8x²-26x+15.
For (7x+4)(-3x+3), the result is -21x²+9x+12.
The multiplication of (-3x-5)(6x+5) yields -18x²-45x-25.

Factoring Out GCF (Greatest Common Factor)

The expression -2x²-4x+2 factors to -2(x²+2x-1).
Factor out the GCF from -45x⁵+63x³-81x², resulting in -9x²(5x³-7x+9).
The expression 12x³+20x+10 can be factored to 2(6x³+10x+5).
From -2x⁴+8x²-14x, the GCF is -2x(x³-4x+7).

Complete Factoring

The expression 3x²+24x-27 can be factored completely as 3(x+9)(x-1).
Factoring x²-5x+4 results in (x-4)(x-1).
The expression x²+5x-24 completely factors to (x+8)(x-3).
The expression 4x²-12x-216 simplifies to 4(x-9)(x+6).
From 42x²-228x+216, complete factoring gives 6(7x-6)(x-6).
The expression 3x²+2x-21 factors completely into (3x-7)(x+3).
24x²-28x-80 can be completely factored to 4(3x+4)(2x-5).
The expression 12x²+84x+135 factors to 3(2x+9)(2x+5).

Solving Quadratic Equations

The equation 4x²-4x=48 has solutions x=4 and x=-3.
Solving 7x²=42-7x yields x=2 and x=-3.
For 6x²+6x=0, solutions are x=-1 and x=0.
The equation x²+6=-7x results in x=-1 and x=-6.
