When you make the product of a binomial of the kind x + a times other binomial that is of the kind x - a, you obtain another binomial (not a trinomial), so any example with that form will be a counterexample that disproves the conjecture:

(x + a) * (x - a) = x^2 - a^2

For example, (x +3) * (x - 3) = x^2 - 9. So, not always the product of two binomials is a trinomial.

Written as a simplified polynomial in standard form, what is the result when (2x - 7) ^ 2 is subtracted from 1?
zaharov [31]

Answer:

ans: -4( x-3 )( x-4 ) I.e -4( x² + x - 12 )

Step-by-step explanation:

as per question

1- (2x-7)²

= (1 + 2x - 7)(1- 2x + 7)

= ( 2x - 6)(-2x +8)

= -4(x-3)(x+4)

Calculate (228, 432, 320) in two ways: using Euclidean algorithm, and by factorization.
frez [133]

Answer:

4

Step-by-step explanation:

gcf(432,320,228)=gcf(gcf(432,320),228)

432=320(1)+112

320=112(2)+96

112=96(1)+16

96=16(6)

So the gcf(432,320)=16.

So now we need to find gcf(16,228)

228=16(14)+4

16=4(4)

Therefore,

gcf(432,320, 228)

=gcf(gcf(432,320),228)

=gcf(16, 228)=4

===================================

432=4(108)=4(2)(54)

=4(2)(6)(9)=2(2)(2)(2)(3)(3)(3)

320=4(80)=4(2)(40)=2(2)(2)(4)(10)

=2(2)(2)(2)(2)(2)(5)

228=4(57)=2(3)(38)=2(2)(3)(19)

All three of them have 2*2 in commom, so the greatest common factor is 4.
