Factoring Polynomials x^2 +bx + c

TRUE OR FALSE: When the values of both b and c are positive, the second terms of the binomials are both positive.
EXAMPLE: x^2 + bx + c = (x + b) (x + c)
EX1: x^2 + 9x + 14 = (x + 7) (x + 2)

• TRUE

• FALSE

TRUE OR FALSE: When the value of b is negative but the value of c is positive, the second terms of the binomials are both negative.
EXAMPLE: x^2 - bx + c = (x - b) (x - c)
EX1: x^2 -7x + 10 = (x - 5) (x - 2)

• TRUE

• FALSE

TRUE OR FALSE: When the value of c is negative, the second terms of the binomials have the same sign.
EXAMPLE: x^2 + bx - c OR x^2 - bx - c IS (x - b) (x - c) OR (x +b) (x +c)
EX1: x^2 - 5x - 14 = (x + 7) (x + 2)

• TRUE

• FALSE
