X²+5xy+6y²=0
Calculate the values of x and y if x+y=8​

Mr. walker gave his class the function f(x) = (x + 3)(x + 5). four students made a claim about the function. each student’s claim is below. jeremiah: the y-intercept is at (15, 0). lindsay: the x-intercepts are at (–3, 0) and (5, 0). stephen: the vertex is at (–4, –1). alexis: the midpoint between the x-intercepts is at (4, 0). which student’s claim about the function is correct?

Y=(x+3)(x-4)(x+1)^2 sulutions? multiplicity?

Pls never taught i’m really confused and i rlly need
