Answer: x2+10x-75= (x-5)(x+15)
Step-by-step explanation:
Ok so we factor by thinking of numbers that can add to 10 and multiple to get -75. so those 2 numbers were -5 and 15. Hope this helps xD
Answer:
(x+15)(x-5)
x²+10x-75= x²+15x-5x-75
=x(x+15)-5(x+15)
=(x+15)(x-5)
the standard form of the equation is: a. y=7x^2-42x+67
