Find the quadratic equation if its solutions are 1.5 and -.25, and the equation coefficients are not decimals.

If a quadratic equation has solutions and , then we can write it as

So, in your case, we have (let me write 1.5 as 3/2 and -0.25 as -1/4)

If we don't want decimal coefficient, we can multiply the whole expression by 8:

-3.396 = -3.4

-0.708 = -0.7

0.304 = 0.3

0.955 = 1
