Find the values for "a" and "b" that would make the equality true -5(3x^2+5x+b)=ax^2-25x+45 a= b=

a = - 15 and b = - 9

distribute the left side of the equation

- 15x² - 25x - 5b

for - 15x² - 25x - 5b and  ax² - 25x + 45 to be equal then the coefficients of like terms must be equal, hence

- 15x² = ax² ⇒ a = - 15

- 5b = 45 ⇒ b = - 9

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
