Rewrite 2x^2+9x-5 in factored form then find x-intercepts and vertex and graph the function
Here is your quadratic equation factored:
Factor the following:
2 x^2+9 x-5
Factor the quadratic 2 x^2+9 x-5. The coefficient of x^2 is 2 and the constant term is -5. The product of 2 and -5 is -10. The factors of -10 which sum to 9 are -1 and 10. So 2 x^2+9 x-5 = 2 x^2+10 x-x-5 = 5 (2 x-1)+x (2 x-1):
5 (2 x-1)+x (2 x-1)
Factor 2 x-1 from 5 (2 x-1)+x (2 x-1):
Answer: | (2 x-1) (x+5)
