;i’m hopeless. find the value of c that makes each trinomial a perfect square. then write the trinomial as a perfect square. 10. x^2-14x+c 11. x^2+24+c 12. x^2+5x+c 13. x^2 -9x+c 14. x^2-x+c 15.

Well, you have to find 2 of the same number that add together to make that middle number before the c. Then you have to multiply those 2 identical numbers together to find the value of c!——————————————————————So! For number 10, 7+7 is 14, so 7 and 7 are your two identical numbers.——————————————————————Then you have to multiply them to get c! 7•7=49, so 49 is c.——————————————————————I’ll do 11 for you as well, 12+12=24, and 12•12=144, so 144 is c.
