How would you find the zeros of the function by rewriting the function in intercept form? ex: y=x^2 + 10 + 25

That means you factor it which finds the zeros of the function. That's what factoring a quadratic does...finds the zeros of the function, the places on the graph where the function goes through the x-axis. This function needs 2 numbers that add up to equal 10 and multiply to equal 25. Both signs are the same and they're both positive so the factors are (x + 5)(x + 5). Setting those equal to zero according to the zero product property, x + 5 = 0 so x = -5 with a multiplicity of 2. The intercept form is the one with the parenthesis still there. It could also be simplified as (x + 5)^2

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
