Answer:
1. (x-13)(x-9)
2.(z-6)(z+25)
3.(x-10)(2x+3)
Step-by-step explanation:
1.x²-22x+117 = x²-9x-13x+117
= (x-13)(x-9)
2.z²+19z-150 = z²+25z-6z-150
= (z-6)(z+25)
3.2x²-17x-30 = 2x²+3x-20x-30
= (x-10)(2x+3)

Answer:
1. x² - 22x + 117
x² - 13x - 9x + 117
x(x - 13) -9(x - 13)
(x - 9)(x - 13)
x - 9 = 0 x - 13 = 0
x = 9 x = 13
x = 9,13 ans.
2. z² + 19z - 150
z² + 25z - 6z - 150
z(z + 25) -6(z + 25)
(z - 6)(z + 25)
z - 6 = 0 z + 25 = 0
z = 6 z = - 25
z = 6,-25 ans.
3. 2x² - 17x - 30
2x² - 20x + 3x - 30
2x(x - 10) +3(x - 10)
(2x + 3)(x - 10)
2x + 3 = 0 x - 10 = 0
2x = -3 x = 10
x = -3/2 x = 10
x = -3/2,10 ans.
