Question

The factors of x ( 12x + 7 ) - 10 is

Answer 1

Answer:

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

Step-by-step explanation:

12x2+7x-10

12x2+15x-8x-10

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

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

Answer 2

Step-by-step explanation:

x(12x+7)-10

=12x²+7x-10

here ,

a=12, b=7, c =-10

x=(-b±√b²-4ac)/2a

x=(-7±√7²-4x12x-10)/2×12

x=(-7±√49+480)/24

x=(-7±(√529)/24

x=(-7±23)/24

x=30/24,x=16/24
