Answer 1

Answer:

(2x + 5)(3x - 7), (x + 4)(x - 2)

Step-by-step explanation:

a = 6, b = 1, c = -35

? × ? = ac = 6 × -35 = - (2 × 3 × 7 × 5)

? + ? = b = 1

3 × 5 -(negative sign from above) 2 × 7 = 15 - 14 = 1 = b

$\frac{1}{6}(6x + 15)(6x + (-14))$

= $\frac{1}{6}(3)(2x + 5)(2)(3x - 7)$

= $(2x + 5)(3x - 7)$

a = 1, b = 2, c = -8

? × ? = ac = 1 × -8 = -(2 × 2 × 2) = 4 × -2

? + ? = b = 2

4 + (-2) = 2 = b

$\frac{1}{1}(1x + 4)(1x + (-2))$

= $(x + 4)(x - 2)$
