Respuestas a la pregunta
•X= 0 X =2
• x= 0 x = 4
• x = 0 x = 4
• x = 0 x = - 4
•x = 0 x = 2
• x = 0 x = 81
Explicación paso a paso:
15.) x²-2x = 0
• Factoriza x
x (x-2)=0
•Iguala a 0
x = 0 x -2=0
x = 2
16.)4x²-16x = 0
• Factoriza 4x
4x (x - 4 ) = 0
• Divida entre 4
x (x - 4) = 0
• Iguala a 0
x = 0 x - 4= 0
x = 4
17.)5x²-20x = 0
• Factoriza
5x (x - 4) = 0
• Divide 5
x (x - 4) = 0
• Iguala a 0
x = 0 x - 4 = 0
x = 4
18.)6x²+24x = 0
• Factoriza
6x ( x + 4) = 0
•Divide 6
x ( x + 4) = 0
• Iguala a 0
x = 0 x + 4 = 0
x = - 4
19.) 7x² - 14x = 0
• Factoriza
7x (x - 14) = 0
• Divide 7
x (x - 2) = 0
• Iguala a 0
x = 0 x = 2
20.)x² - 81x = 0
• Factoriza
x ( x - 81) = 0
• Iguala a 0
x = 0 x - 81 = 0
x = 81
